Parallax Zoom improves the appearance of maps visually when zooming.
Contrary to initial tests, it does not interfere with certain map
locations such as the shop on the map Timeshop.
The default value appears to be correct for all existing maps.
The value in the map file is non-trivial to manage, and provides little
benefit. See https://github.com/ddnet/ddnet/issues/6196 for further
discussion.
The entire `CEditorImage` was being overwritten when loading external images, which was causing the already loaded image name to be cleared, due to the changed order of operations (regression from #7008). This is fixed by using `CImageInfo` to load the image and only copying the relevant members to the `CEditorImage`.
Simplify the usage of datafile reader and writer by adding utility functions to read and write zero-terminated UTF-8 strings.
Improve validation of string data read from datafiles. It is ensure that string data is null-terminated, has no internal NUL-characters and is valid UTF-8.
Fix loading of external sounds in the editor. The wrong path variable was being used, so the sound files would not be loaded from correct folder.
Add tests for new datafile reader/writer functions.
Add error message in editor when loading a map that has an unsupported version.
Ensure error messages are not closed immediately when loading a map fails.
Remove unnecessary indentation by returning early.
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.
