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.

Currently, scaling doesn't work correctly on macOS (see #5185). This commit
works around this issue by disabling SCALE_FRAMEBUFFER on macOS when
`FLAG_WINDOW_HIGHDPI` is unset.
* win32 backend
* [rcore][win32] use SwapBuffers instead of wglSwapLayerBuffers
I don't understand OpenGL well enough to know the difference between
SwapBuffers and wglSwapLayerBuffers but the former seems to double
my FPS (from 2000 to about 4000 in core_vr_simulator).
* [rcore][win32] stop lying to the OS about when our window is updated
Instead of calling BeginPaint/EndPaint in WM_PAINT which signals to the
OS that our window content is updated, now when we encounter the WM_PAINT
message instead we return back to the raylib application which will
trigger it to render a new frame. We've replaced the call to BeginPaint
and EndPaint with a call to ValidateRect in SwapBuffers, which, means
we're now correctly telling the OS when our window content is actually
up-to-date.
Note that this doesn't fix the window content not being updated during
a window resize/move beacuse thos have their own message loop which
doesn't return early when it's time to paint.
* [rcore][win32] fallback to finding functions from opengl32.dll
* [rcore][win32] fixes from review/for gcc
* [rcore][win32] incorporate style conventions
* [rcore][win32] workaround unused function error SetupFramebuffer
* [rcore][win32] re-enable sanitize flags check for MSAA_4X
* [rcore][win32] more style changes and remove old DPI cases
Added some more missing spaces after conditional statements. Also
made unsupported MSAA_4X an assert instead of an abort and also
removed dpi-aware cases for older OS's. More changes would be needed
to support those OS versions, namely, removing the dependency
on shcore.
* [rcore][win32] fixes for compling with w64devkit without -DUNICODE
* Update build.zig
* Update build.zig

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.
The original implementation created/destroyed framebuffers (FBs) per-frame, leading to kernel overhead and screen tearing. This commit replaces it with a different approach using:
- Asynchronous `drmModePageFlip()` with vblank sync
- Framebuffer caching to reduce repeated FB creation/removal operations
- Proper resource management through BO callbacks and buffer release synchronization
- Added error handling for busy displays, cache overflows, and flip failures
- Event-driven cleanup via page_flip_handler to prevent GPU/scanout conflicts

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.
Restore window currently says it sets the window state to:
"not minimized/maximized"
However, if a window is maximized and then minimized, it's typical that
it would restore back to being maximized, which is what seems to happen
from my testing. I've reworded the description to better reflect
this behavior.
raylib app crashing when started and a gamepad is already connected to the PC (even if the gamepad is not used in the app). I only tested this with a gamepad that has a layout which is not recognized. Using SDL3 as backend.
This may not be the correct approach, however this appears to work. The idea is that before modifying `CORE.Window.flags` when first creating the window we keep a copy of the flags in order to call `SetWindowState` after initialization has completed, which should behave as if `MaximizeWindow` or `MinimizeWindow`, or conceptually any other flag modifying function were called after `InitWindow`.
This pull request only performs this for the windows platform, modify as needed in the switch statement at the end for others.
Raylib allows for providing custom allocators via macros.
GLFW supports this too, but via function pointers.
Make sure that GLFW uses those Raylib macros, by wrapping them in
function calls and setting them up inside of InitPlatform().
This is possible because of glfwInitAllocator() and GLFWallocator.

This change is replacing the hardcoded "#canvas" element references in
rcore_web to allow using canvas elements that use different names
(which is necessary when using multiple canvas elements on one page).
Also adding a cursor hiding example to mouse example.

CORE.Window.position is now properly kept in sync with the glfw window position.
* Update rcore_desktop_glfw.c
Comments updated.
* Setting CORE.Window.position correctly in InitPlatform() as well.
This also fixes not centering the window correctly when the high dpi flag was enabled.
* Fixes centering the window in the SetWindowMonitor() function.
Here the render size has to be used again in case the high dpi flag is enabled.
* Update Window Position
Update Window Position right away in ToggleFullscreen() & ToggleBorderlessWindowed() functions
* GLFW AUTO_ICONIFY flag is now set to false per default.
Previously AUTO_ICONIFY was only disabled if the user requested a Fullscreen window from the start. After that it was not possible to change this behavior on the user side anymore, even when changing to a Fullscreen window.
The AUTO_ICONIFY causes problems on macOS. On macOS if the window is minimized because of AUTO_ICONIFY than the only way to restore it is to click on the icon in the dock. In other words when AUTO_ICONIFY is enabled alt/cmd-tabbing through windows does not work correctly. On windows it works even when AUTO_ICONIFY is enabled.
Additionally if a raylib window is in Fullscreen mode on another monitor the AUTO_ICONIFY behavior is a problem because the user might want to window to stay on the monitor even if it loses focus. (problem on all OS's)
AUTO_ICONIFY also restores the monitor hardware resolution if a fullscreen window loses focus.
* Update rcore_desktop_glfw.c
Extra space removed and comments updated with a space at the beginning
If `FLAG_WINDOW_HIGHDPI` is set, `InitPlatform()` will aks GLFW to handle resize window content area based on the monitor content scale using : ` glfwWindowHint(GLFW_SCALE_TO_MONITOR, GLFW_TRUE); `
So `WindowSizeCallback()` does not have to handle it a second time.
This could potentially be a breaking change, for consistency, now every possible desktop backend has the proper name assigned: GLFW, SDL, RGFW
raylib build system has been reviewed to fallback to `PLATFORM_DESKTOP_GLFW` by default when `PLATFORM_DESKTOP` defined
* Fix Makefile issues (RGFW) (linux) (macOS)
* Do not use nanosleep on windows at all (PLATFORM_DESKTOP_RGFW)
