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.
This still works
$ ./DDNet "connect 127.0.0.1"
But now also this works

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.
`shared_ptr`s of `CServer::m_pDnsblLookup[ClientID]` are set, but not
cleaned up when done. Therefore the Job is kept alive until the player
disconnects and a new player joins on that slot. Currently this means
that the full linked list of jobs is kept alive.
When the Job is overwritten with a new job, all the remaining objects in
the list can be dropped. With enough jobs, that is causing a stack
overflow in the destructor.
This patch fixes this overflow by making the lifetime independent of the
previous Job. Jobs can get dropped after processing them, even when the
previous job is still alive.
Fixes#6954
The old code looked pretty weird. It checked for `CFGFLAG_SERVER |
CFGFLAG_GAME` being set above, and then used the passed-in parameter to
find the command. I think it'd be better to just look for `CFGFLAG_GAME`
and then find the command using `CFGFLAG_GAME`.
Check if datafile data cannot be read entirely (according to the data size specified in the header) and check for decompression errors. In case of errors, let `GetData` return `nullptr` and `GetDataSize` return `0` for the respective index.
Internally the decompressed size is set to `-1` for data which failed to load, so loading of those data will not be attempted again because it would only fail again and can cause additional log messages.
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.
Use icons for all server settings buttons. Rearrange and group buttons.
Show buttons in disabled state when they are not useable instead of hiding them.
Remove checker background from server settings list.
Overhaul hotkeys, also show hotkeys in the tooltips:
- Enter: add command
- Alt+Enter: update command (previously M)
- Alt+Up/Down: move command up/down (previously no hotkey)
- Delete: delete command
Don't activate command lineinput when selecting, moving or deleting elements, as this prevents the listbox from accepting the delete hotkey.
Fix server settings listbox being active while file dialog is open.
Ensure extra editor dragbar area matches the respective toolbar size.
Remove spacing on the left side of extra editors to improve alignment.
Increase status bar button sizes and make them consistent.
Use `enum` to track active extra editor instead of using multiple `bool`s.
Disable extra editor buttons when tile picker is shown, as the extra editors are not rendered in this case.
Port the `CJsonWriter` utility class from upstream, which makes outputting correct JSON easier.
Add `CJsonWriter` as an abstract class that can write to different outputs. Two implementations `CJsonFileWriter` (writes to a file) and `CJsonStringWriter` (writes to an `std::string`) are added. Upstream `CJsonWriter` can only write to files.
The same tests are added for both implementations. Duplicate code is avoided by using typed tests with two separate test fixtures.
`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.
Port map and editor support for `CURVETYPE_BEZIER` from upstream, i.e. support bezier curves with configurable in- and out-tangents for every envelope point.
The in- and out-tangents are represented by triangles and can be dragged in the envelope editor like the envelope points.
Support reading and writing the bezier information as a separate UUID-based map item. If the bezier information is not found, bezier will default to linear behavior. Old clients will still be able to read the new maps and ignore the unknown map item. The unknown curvetype will also be handled as linear by old clients.
Allow reading upstream maps that use `CMapItemEnvelope` version 3. On upstream, a different struct is used to store all envelope points including bezier information, which broke compatibility to old clients.
Fix holding Ctrl for slow envelope point editing not working for vertical movement.
Highlight the currently selected element (envelope point or bezier tangent marker) which is being used with the value/time edit boxes.
Hide the value/time edit boxes when no element is selected.
