[utils] was created long time ago, when [rcore] contained all the platforms code, the purpose of the file was exposing basic filesystem functionality across modules and also logging mechanism but many things have changed since then and there is no need to keep using this module.
- Logging system has been move to [rcore] module and macros are exposed through `config.h` to other modules
- File system functionality has also been centralized in [rcore] module that along the years it was already adding more and more file-system functions, now they are all in the same module
- Android specific code has been moved to `rcore_android.c`, it had no sense to have specific platform code in `utils`, [rcore] is responsible of all platform code.
When SDL_GameControllerNameForIndex returns null, the app crashes. This was addressed earlier in PR#4859 though the fix submitted on PR #4859 was only fixing the crashing and not addressing the root cause.
* use FLAG_* macros where possible
* rename `FLAG_CHECK()` to `FLAG_IS_SET()`
* remove unnecessary equality checks
* fix issues

SDL3 uses ID when dealing with monitors, unlike SDL2 which uses Index
for the same thing. This problem was already fixed in multiple places
by use of preprocessor branches, so I did the very same thing.
Please, notice that this is a pretty bad solution to this problem,
and I only did it to keep it consistent with the rest of the code.
The more about why it's not correct is mentioned here:
https://github.com/raysan5/raylib/issues/5256#issuecomment-3429156919
Hopefully, someone will refactor it someday :)
Fixes: https://github.com/raysan5/raylib/issues/5256
* add base of rlsw.h
* implement state support
Also replace the triangle rasterization functions with macros that generate specific functions for each state of the rendering system.
Also, add the OpenGL definitions in order to add a binding for rlgl.
* branchless float saturation
* apply perspective correction to colors
* impl line clipping and rasterization
+ tweak function names
* impl face culling
* impl color blending
* fixes and tweaks
* add clear buffer bitmasks
* small optimizations / tweaks
* review ndc to screen projection
* avoid to recalculate MVP when its not needed + tweaks
* review the loading and management of textures
to be closer to the OpenGL API
* texture sampling optimization
* review get pixel functions
+ review unorm/float conversion
* add several buffer format support
Several depth and color formats have been added for the framebuffer.
8-bit, 16-bit, and 24-bit formats are now available for depth.
RGB 8-bit (332), RGB 16-bit (565), and RGB 24-bit (888) formats are now available for color.
Alpha support is no longer present for the framebuffer at the moment, but it can easily be restored by adding the formats and reinterpolating the alpha in the areas that do not perform color blending.
Additionally, this commit brings performance improvements.
* tweaks
* impl line width
* impl points + point size
* fix and improve polygon clipping functions
* impl polygone modes
* add some not planned functions
- `glDepthMask`
- `glColorMask`
* framebuffer resizing + handle init failure
* add quick notes about line clipping algorithms used
* start to impl scissor test + review line clipping
The support for the scissor test has been implemented for clearing as well as for triangle clipping.
The implementation for lines and points is still missing.
I also removed the 2D clipping of lines that used the Cohen-Sutherland algorithm, opting instead to always use the Liang-Barsky algorithm in all cases.
This simplifies the implementation, and the 2D version would have caused issues when interpolating vertices in the future if we want to implement additional features.

Added CMake support for SDL3.
Now supports including SDL2 or SDL3 as a subdirectory within the project. The system will first check for SDL3, then SDL2. If neither is found, it will attempt find_package(SDL3), followed by find_package(SDL2). If all these checks fail, the process will terminate with an error.
I believe it makes sense to only do this when there are no known
touch points. I am not even sure if this should be done at all.
See https://github.com/raysan5/raylib/issues/4872 for more information.
