Use config manager to reset `ui_page` to the default, instead of using `CMenus::PAGE_DDNET` directly (which is the default).
Check current type of serverbrowser instead of checking the current `ui_page` against `CMenus::PAGE_DDNET` and `CMenus::PAGE_KOG`.
Using `dbg_stress 1` now only does the following (in debug build):
- Randomly send inputs.
- Randomly send chat messages.
- Randomly connect/disconnect to server configured with `dbg_stress_server` (`localhost` by default).
Previously it also did the following, which is not useful for this debugging feature and only complicates the code unnecessarily:
- Cause images and sounds not to be loaded.
- Render only every tenth frame.
- Always use inactive graphics refresh rate.
Instead of keeping track of a permanently empty `CSnapshot` object in client and server separately, add `CSnapshot::EmptySnapshot` to access a singleton empty `CSnapshot`.
Mark pointer parameters of snapshot functions as `const` when possible.
Simplify the handling of free texture indices by using `-1` only for indices which are currently in use, whereas the size of the vector is now used to indicate the last free index. Otherwise the assertions incorrectly detect the last texture index always being in use because `-1` was used for both states.
Most variables used in the sound engine were static globals, as they are used in the static sound mixing function. The global variables are replaced by member variables, by passing the sound interface as user-data for the SDL mixing callback. The `Mix` function is made a public member function of `ISound` instead of being exposed using `ISoundMixFunc GetSoundMixFunc()`.
This allows to remove the direct dependency of the engine sound on the engine video, by instead passing the sound mixing function as a lambda to the engine video in the engine client.
The old WavPack reader function interface does support passing a user-data pointer to the callback function, so global variables are still used here.
Replace existing hard-coded support for two "networks" with support for a dynamic list of "communities" which are indexed by a string-ID, though right now the DDNet and KoG communities are still hard-coded. The communities now also support an arbitrary number of associated countries, types and servers. This is a refactoring to prepare for getting the list of communities dynamically from the server and removing the DDNet and KoG tabs from the serverbrowser.
Check if maximum number of lines has been reached before starting a new line, to prevent the text cursor from reporting the wrong number of lines and text height in that case.
Use `enum EImageFormat` type for image format literals and variables.
Add `PixelSize` function to get the number of bytes/color channels per pixel for a specified image format.
Remove unused store format argument of texture loading functions. All textures are automatically being stored as RGBA, so the argument was unused. Also remove the therefore unused `FORMAT_AUTO`.
Rename variables consistently to `PixelSize` and use `size_t`, instead of mixing different names like `BPP` and `ColorChannelCount`.
Validate image format loaded from maps using `CImageInfo::ImageFormatFromInt`. Add `FORMAT_ERROR` to represent invalid formats.
Remove redundant `PixelSize` parameter from graphics backends and commands, which can be derived from the texture format.
Fix memory leak when RGB image data is being converted to RGBA format when saving map in editor.
This config variable was only settable in the server console but only read in the client, so it was effectively unusable. It also has no use case right now.
The log message is otherwise shown multiple times when starting the client.
Now it's only shown when the `record` command is used manually, i.e. not for automatically recorded demos anymore.
Add `str_utf8_offset_bytes_to_chars` and `str_utf8_offset_chars_to_bytes` functions to base system to convert between byte and UTF-8 character offsets in UTF-8 strings.
Previously, this was separately implemented in the textrender and in the lineinput helper.
These textrender functions are entirely replaced by the new functions:
- `ITextRender::SelectionToUTF8OffSets` (by `str_utf8_offset_chars_to_bytes`)
- `ITextRender::UTF8OffToDecodedOff` (by `str_utf8_offset_bytes_to_chars`)
- `ITextRender::DecodedOffToUTF8Off` (by `str_utf8_offset_chars_to_bytes`)
These lineinput helper functions are reimplemented using the new functions:
- `CLineInput::OffsetFromActualToDisplay` (uses `str_utf8_offset_bytes_to_chars`)
- `CLineInput::OffsetFromDisplayToActual` (uses `str_utf8_offset_chars_to_bytes`)
Register the `OnWindowResize` listener in the engine client instead of the game client and properly dispatch the event also to the editor, so text containers in the editor are cleared when the window is resized.
Closes#7018.
Fix text containers rendering broken text after the language is changed, as this cleared the glyph atlas without clearing the references to the glyph positions in the text containers. Now `OnWindowResize` is also called on language change to reset all text containers.
However, the glyph atlas is not cleared on normal window resize anymore, because this seems to be unnecessary.
Replace skyline-based texture atlas algorithm with a rectangle packing algorithm that tracks empty atlas sections using `std::vector`s. The algorithm is very loosely inspired by https://github.com/TeamHypersomnia/rectpack2D.
Increases texture atlas utilization from ~70% to ~90-94%, i.e. less space in the atlas is unused.
Decreases the computational time to find suitable free regions in the atlas by factor 40x-164x (depending on atlas dimension and utilization). In absolute numbers, the computational time necessary for a glyph being added to the atlas is decreased from 0.0556ms-0.4679ms to 0.0013ms-0.0051ms (depending on atlas dimension and utilization).
The memory usage for the texture atlas algorithm increases from a maximum of ~128 KB to a maximum of ~3 MB.

Add `fonts/index.json` which specifies:
- List of all font files that should be loaded (filenames).
- Default font (specified by family name or by family and style name).
- Font variants for different languages, using the name of the language file as key.
- Fallback fonts.
- Icon font.
There are characters (e.g. all in `刃直海角骨入`) that look different depending on the language of the content being Japanese, Simplified Chinese, Traditional Chinese and Hangul, because Unicode uses the same codepoint for characters regardless of the language. To render these characters correctly, the active variant font is switched depending on the selected language.
The `ITextRender` interface is changed so the current language variant can be set using `SetFontLanguageVariant` and the default and icon fonts can be toggled using `SetFontPreset`. The class `CFont` is removed entirely.
The text render is restructured: The font faces and font atlas are now managed by a separate class `CGlyphMap` like on upstream. As the text fill and outline textures always have the same size, the texture skyline only needs to be stored once and free positions in the atlas only need to be calculated once for each glyph instead of separately for the fill and outline textures.
The font files and their licenses are also updated:
- Update Source Han Sans to version 2.001.
- Update Glow Sans Japanese Compressed to version 0.93.
- Update Deja Vu Sans to version 2.37.
- Update Font Awesome icons font to March 2023 version.
Closes#6881.
Rectangles with inverted round corners (`IGraphics::CORNER_I*`) are currently not used anywhere and also only supported when using `Draw4`.
They also feel clunky to use due to the inverted corners being drawn outside of the specified rectangle area.
`stdout_output_level` for printing to stdout, `console_output_level` for
printing to local console and remote console and `loglevel` for the log
file.
Keep the old log level filters 0 for info and more severe, 1 for debug
and more severe and 2 for trace and more severe, introducing -1 for
warn, and -2 for error. -3 will show no log messages at all.
When memory for a command or data in the command buffer cannot be allocated in `CGraphics_Threaded::AddCmd` and `CGraphics_Threaded::AllocCommandBufferData` the command buffer is cleared so it should always be possible to allocated memory successfully on the second try. Therefore assertions are added and the return values and inconsistent checks of the functions are removed.
The usage of `AddCmd` is simplified by automatically deriving an error message based on the type of the template parameter.
Only add assertion to prevent empty filename, as this causes Valgrind to crash.
Handle empty filename used for special null-image separately in gameclient.
When starting with `dbg_stress 1` the invalid texture was never actually getting loaded, which was causing the client to crash when using the Vulkan backend and starting with `dbg_stress 1`.
Additionally ensure that the invalid texture is 16x16 pixels large and loaded with the texture flags to support usage for tile rendering.
Closes#6504.
Show a short message below the existing chat mentions message that is shown in the top left area of the editor above the layers/images/sounds button when the player character is moved ingame while the editor is open. The messages are cleared when the editor is activated and when the client is disconnected.
Closes#1993.

Minimum SDL version 2.0.16 is required for `SDL_FlashWindow`. The SDL version schema changes after version 2.0.22 to 2.24.0 etc. (minor version is used instead of patchlevel) which was causing the condition that checks for minimum version 2.0.16 to not work correctly with newer SDL versions.

6665: Fix ordering of unfinished/unconnected tees r=heinrich5991 a=Learath2
<!-- What is the motivation for the changes of this pull request? -->
I thought there was initially a strict weak ordering issue here but upon further inspection noticed it's fine.
However, people with negative score were getting sorted undeterministically, basically every unfinished tee was treated as equal since `!comp(a, b) && !comp(b, a)`. Sorting them by name was the intention.
I also got rid of the old `INT_MIN` "hack", it was only there to make the code shorter and it's no longer possible with the newly flipped sign without flipping it back on the client which is ugly.
Also made `ScoreKind` `const`, not sure if any compiler optimizes on that but why not? If we ever move to C++20 this could be a generic lambda instead where we can template `ScoreKind` and make sure it gets optimized properly.
Tidbit: I treated score 0 as a normal score, I'm not sure what it implies.

6673: Clear Victim Team render info on skin changes r=Robyt3 a=Jupeyy
fixes#6662
This should fix the issue, I guess, by simply clearing the render info. I can't find an easy way to restore the original skins of the team members as we don't save their IDs.
I couldn't directly trigger the assert, but I could certainly see the skin getting invalid when killen the team and switch to "vanilla only skins". (Edit: When triggering it a few times I got the assert)
The code generally looks a bit hacky. Maybe the original author can refactor it a bit

6602: Revert "Delay disconnecting until after render call" r=def- a=Robyt3
This reverts commit 5c90fd2b83.
Delaying the disconnecting causes issues when the client automatically disconnects immediately before connecting to another server or starting demo playback.
It's not necessary to delay the disconnecting to deal with #6387, as #6589 is already enough. It's easier to revert this instead of rewriting the client so connecting and starting demo playback are also delayed.
Closes#6595.

6565: Delay disconnecting until after render call r=def- a=Robyt3
When a client component (e.g. the menu or the console) disconnects the client, this immediately unloads the map data but the render call continues as normal. This causes all components rendered after this component to access invalid memory in place of the map, layers and collision data.
This is fixed by delaying the actual disconnecting until after the render call, to ensure that the map data can be safely unloaded.
Closes#6387. Closes#3179.

Register SDL for cleanup before creating the kernel and client, so SDL is shutdown after kernel and client. Otherwise the client may crash when shutting down after SDL is already shutdown.
Closes#6581.
Track stack of cleaner functions that destruct client components so exactly the correct cleanup is performed in the reverse order of initialization.
This allows performing the cleanup also in the early-return cases without introducing duplicate code.
When the configuration file exists but cannot be loaded, the client continues to launch. When closing, the client then saves the default config and overwrites the existing config that could not be loaded.
This is prevented by quitting the client with an error message popup when the config exists but cannot be loaded.

Add missing checks to ensure valid text container index before rendering FPS and finish time text containers.
To show an error/warning/information message popup with variable title and message.
This uses the SDL function `SDL_ShowSimpleMessageBox` to show the message box, because it is simpler than implementing this ourself in the base system, especially because we would have to add an additional explicit dependency on GTK3 to show a message dialog on Linux.

The `Disconnect` function did not fully clear all server data, because the client state was already set to offline manually before the function is called. This was causing inconsistent behavior when connecting to another server after being disconnected. For example, the client could get stuck at "getting game info" when connecting the next time.
SDL fixed the bug on Windows that releasing the mouse while tabbing out directly refocuses the window, which broke desktop fullscreen (and maybe windowed fullscreen)
Port the line input (UI edit boxes, chat, console) and Input Method Editor (IME) support from upstream. Closes#4397.
General
------------------------------
Fix issues with the text input. Closes#4346. Closes#4524.
Word skipping (when holding Ctrl) is overhauled to be consistent with the Windows / Firefox experience that I took as reference.
Improve usability by not blinking (i.e. always rendering) the caret shortly after is has been moved.
UI text input
------------------------------
Fix inconsistent mouse-based left and right scrolling (closes#4347).
Support smooth left and right scrolling.
Chat
------------------------------
Support keyboard-based text selection of the chat input.
Mouse-based selection could be support in the future when we decide to add something like an ingame UI cursor.
Support smooth up and down scrolling of the chat input, removing the old hack that offsets the input string to simulate scrolling.
Console
------------------------------
Also support mouse-based text selection of the command input.
Only text from either the command input or the console log can be selected at the same time. This ensures that Ctrl+C will always copy the text that is currently visually selected in the console.
Check for Ctrl+C input event in event handler instead of in render function, to hopefully fix the issue that copying does not work sometimes (closes#5974 until further notice).
When Ctrl+C is used to copy text from the console log, the selection is cleared. This should make it more clear when text was copied from the log.
Fix an issue that was preventing the console log selection from being cleared, when all log lines are selected.
Remove Ctrl+A/E hotkeys that move cursor to beginning/end respectively. Ctrl+A now selectes all text like for all other inputs. Home and End keys can still be used to go the beginning and end.
Remove Ctrl+U/K hotkeys that clear everything before/after the cursor respectively. Hold shift and use Home/End to select everything instead.
IME support
------------------------------
Render list of IME candidates in the client on Windows, so the candidate list can also be viewed in fullscreen mode. There is no API available to retrieve a candidate list on the other operating systems.
Improve composition rendering by underlining the composition text instead of putting it in square brackets.
Track active input globally to properly activate and deactivate IME through the SDL functions.
Closes#1030. Closes#1008.
Password rendering
------------------------------
Fix rendering of passwords containing unicode. Instead of rendering one star character for each UTF-8 `char`, render on star for every unicode codepoint.
Show the composition text also for passwords. Without seeing the composition text it's hard to type a password containing those characters. The candidate window exposes the composition anyway. If you don't want to expose your password this way, e.g. while streaming, you could:
1. Use a latin password and switch off the IME for the password input with the IME hotkey.
2. Blank your screen with an external program while you are streaming and entering passwords.
3. Use binds to authenticate in rcon or to set the server browser password.
Refactoring
------------------------------
Move all text input logic and general rendering to `CLineInput`.
A `CLineInput` is associated with a particular `char` buffer given as a pointer either in the constructor or with `SetBuffer`. The maximum byte size of the buffer must also be specified. The maximum length in unicode codepoints can also be specified separately (e.g. on upstream, name are limited by the number of unicode codepoints instead).
Add `CLineInputBuffered`, which is a `CLineInput` that own a `char` buffer of a fixed size, which is specified as a template argument. As `CLineInput` does not own a buffer anymore, this reduces duplicate code for line inputs that need their own buffer.
Add `CLineInputNumber` which has additional convenience functions to consider the text as an `int` or `float`, to reduce duplicate code in those cases. In the future we could also add an input filter function so that only numbers can be entered in the number input.
Add `CLineInput::SetClipboardLineCallback` to handle the case that multiple lines of text are pasted into a lineinput. This reduces duplicate code, as this behavior was previously implemented separately for chat and console. The behavior is also fixed to be consistent with the console on Windows, so the first line being pasted edits the current input text and then sends it instead of being sent on its own without the existing input text.
Add `CalcFontSizeAndBoundingBox` to UI to reduce duplicate code. Expose `CalcAlignedCursorPos` as static member function to reuse it for line input.
Dispatch input events to UI inputs through the event handler instead of storing them in a duplicate buffer.
Use `size_t` for line input cursor position, length etc. and for `str_utf8_stats`.
Add `IButtonColorFunction` to UI to describe a functions that defines colors for the Default, Active and Hovered states of UI elements. Add some default button color functions. Use button color function to reduce duplicate code in scrollbar rendering.
Use `vec2` instead of two `floats` to represent the mouse positions in the text renderer.
Remove `CaretPosition` again, as it does not calculate the correct Y position near line breaks due to the wrapping being different when not rendering the entire string. Instead, calculate the exact caret position when rending a text container and store the caret position in the text cursor for later use.
IME usage guide (Windows)
------------------------------
1. Install the respective language and the Microsoft-IME keyboard (e.g. for Chinese, Japanese or Korean).
2. Launch the game (or a text editor to first try out the IME). Note that Windows may track the input language separately for every application. You can change this in the Windows input settings so the input language is changed globally.
2. Switch the input language using the hotkey Windows+Space or another hotkey that you configured in the Windows input settings (Alt+Shift is the default, but you should consider disabling it, to avoid accidentally changing the input language while playing).
3. Switch from Latin/English input mode to the respective asian input mode.
- Chinese: Use Ctrl+Space to switch between English and Chinese input mode. You can change this hotkey in the IME's settings.
- Japanese: Use Ctrl+Space to switch between Alphanumeric and Hiragana/Katakana input mode. You can change this hotkey in the IME's settings.
- Korean: Use Right Alt to switch between English and Hangul input mode. You cannot change this hotkey as of yet.
- Note that the input mode is also tracked per application, but there is no setting to change this behavior as far as I know, so you'll need to switch for every application separately.
4. Start typing. The underlined text is the current composition text. While a composition is active, you can only edit the composition text. Confirm the composition with Space or by selecting a candidate from the candidate list with the arrow keys. Cancel the composition with Escape or by using Backspace to delete the composition text. Note that not all languages offer a candidate list.
SDL version-specific issues
------------------------------
- 2.26.5, 2.24.2, 2.0.22: IME candidates work. But there are minor bugs when moving the composition cursor.
- 2.0.18, 2.0.20: IME candidates work.
- 2.0.16 (our current version): IME candidates cannot be determined with Windows API. Windows tries to draw the composition window like before, so this does not work in fullscreen mode.
- 2.0.8 (upstream 0.7): IME candidates work. But this SDL version is too old for us.
