Invalid UTF-8 will not be read from config files with `CLineReader` anymore and the local console never allowed entering invalid UTF-8, so this additional mangling of invalid UTF-8 string config variable values is unnecessary.
The engine graphics do not need to be involved with freeing image data.
The `Free` function now also ensures that all other member variables are cleared when freeing the image data.
The `unknown address` log message got printed very often because many servers have 0.6 and 0.7 addresses but only 0.6 addresses are considered valid by the client.
Support scrolling all scroll regions with the mouse wheel also while popup menus are open. Support overlapping scroll regions by always scrolling the top-most hovered scroll region on mouse wheel events.
The hot scroll region is now tracked separated by `CUi`, as tracking the IDs of all UI elements which are contained in scroll regions is not feasible. The separate active state for scroll regions is therefore unnecessary.
It's still necessary to disable `CListBox`es when popup menus are open, to ensure that only one list box consumes the key events.
Closes#8087. Supersedes #8090.
Add strict validation for `StrToInts` function. Because this function should only be used with trusted internal strings, assertions are added to ensure that the string is not truncated. Some buffer sizes are adjusted accordingly, so truncation cannot happen.
Add less strict validation for `IntsToStr` function. An additional argument specifying the size of the output buffer is added to assert that the size of the output buffer is sufficient. However, because this function is used to decode data sent by the server and read from maps and ghosts, invalid input data should never result in crashes or invalid UTF-8 strings. The function will now unpack an empty string and return `false`, if the string contains invalid UTF-8.
The inline definition of the functions is not wanted, because it requires adding a `system.h` include in `gamecore.h`. Therefore the tools now have to depend on game-shared, which previously only worked because the functions were inline.
Tests are added to ensure the function still behaves the same as before for valid inputs and correctly handles invalid inputs.
`CNetConsole` will now ignore received lines containing invalid UTF-8 codepoints. Previously, it was possible to crash the server on Windows with Econ commands like `exec <invalid UTF-8>`.
Previously, usage of `void *`, `unsigned char *` and `uint8_t *` was mixed in various places for pointers to raw image data and the pointers ended up being cast to `uint8_t *` at some point anyway. Now only `uint8_t *` is used consistently, which improves type safety and readability. Casts to `uint8_t *` are now only necessary when using `malloc` or when reading data from a map.
Show completion options for key names for all bind commands (`bind`, `binds`, `bind_reset`) in the local console.
At the moment this only works for completing the first key name but not for composite binds that use `+`, which would work differently than other console argument completion.
Unnamed keys (starting with `&`) are not shown as completion options.
Refactor console argument completion to reduce duplicate code.
We want to change the state of the job from `STATE_QUEUED` to
`STATE_RUNNING`, but not from `STATE_ABORTED`. Previously, the code
usedd `exchange` to change the state and compared non-atomically
afterwards. This led to `STATE_ABORTED` being replaced by
`STATE_RUNNING` in a race. With `compare_exchange_strong`, this can no
longer happen.
Fixes#8044.
Fix HTTP client effectively shutting down by entering the `ERROR` state when a request cannot be added. Now only the invalid request is aborted immediately. The `ERROR` state is now only entered when a curl function fails in a way where recovery is not possible.
Fix occasional deadlock when HTTP client is shutting down after entering the `ERROR` state, by also immediately aborting new requests when the HTTP client is already in the `ERROR` state.
Remove unused `CHttp::EState::STOPPING`.
Prevent the `tune_zone` command from being shown and used in the local console, which could cause issues with prediction, by only registering it as a game setting but not as a client command. The command callback is still correctly called when map settings are loaded in the `CGameClient::LoadMapSettings` function.

The color selection should only be shown for normal envelope points but not for bezier control points, because it always changes the previously selected normal envelope point. This caused the client to crash when right-clicking a bezier control point when no normal envelope point was previously selected.
Closes#8020.
When image blitting is supported by the Vulkan backend, the color picker was reading incorrect pixel values, because the offset positions for the blitting region are the positions of the top-left and bottom-right corners, but instead the top-left offset and size (width, height) were passed as arguments.
Closes#8040.
Only building the switch entities layer when the current map has a switch layer (#8011) also does not work, because the entities textures are cached for each type and not reloaded unless the entities are changed manually. First joining a server with a map that does not have a switch layer will cause the textures for the type of that server to be built without the switch entities layer, so the switch entities texture will be missing when joining a server of that type with a map that does have a switch layer.
Instead, the switch entities layer textures are always built now, so the cached entities textures are can be used on all maps of the respective server type. This is expected to slightly increase the total memory usage after joining multiple servers of different types. As before, tiles which are unused are masked unless `m_DontMaskEntities` is set.
Instead of defining the macro `WIN32_LEAN_AND_MEAN` and sometimes also the macro `_WIN32_WINNT` in each file that directly or indirectly includes `<windows.h>`, only define these macros once consistently in `CMakeLists.txt`.
Also define `NTDDI_VERSION`, which is the new macro to specify the minimum Windows version starting with Windows Vista. This macro needs to be defined in addition to old `_WIN32_WINNT` macro, according to the documentation.

Assert on failures in all `thread_*` and `sphore_*` functions on all operating systems instead of only printing log messages on Unix, as these functions are only expected to fail when used with incorrect arguments or in some cases when a dead-lock is detected.
On macOS, `sphore_wait` was not correctly calling `sem_wait` in a loop to repeat the wait operation if it is interrupted by a signal.
On Windows, the AIO tests were failing with the additional assertions. The maximum count that semaphores on Windows could be incremented to was previously, arbitrarily limited to 10000, which was causing the `ReleaseSemaphore` call to fail as the AIO semaphore is signaled 65536 times (for each write operation) in multiple of the AIO tests.
- Remove `ValidateFCurve` function because it's small and only used once.
- Remove unnecessary checks in `SolveBezier`, as all of these conditions are already checked before the function is called.
- Remove unnecessary double negation of `InTang` to improve readability.
- Use `double` literals for `double` comparisons instead of `float` literals.
- Fix comments.
There is no need to divide the times by 1000 when evaluating bezier curves, as all times are relative and the division adds significant inaccuracy, to the point where evaluation of bezier curves goes completely wrong in some cases.
Closes#8005.
