Also, add the OpenGL definitions in order to add a binding for rlgl.

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.

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

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.
* Implementing GetMonitorWidth/Height and GetMonitorPhysicalWidth/Height for drm
Added implementation for DRM for functions :
- GetMonitorWidth()
- GetMonitorHeight()
- GetMonitorPhysicalWidth()
- GetMonitorPhysicalHeight()
- GetMonnitorName()
These functions take an argument but only the value 0 is accepted. This is because the DRM platform implementation manages only one screen for now
* Refactor "GetMonitor" properties for DRM Platform
Refactored GetMonitorHeight, GetMonitorWidth, GetMonitorPhysicalHeight,
GetMonitorPhysicalWidth and GetMonitorName to accept only argument "0"
as more than one screen is not supported in DRM platform.
* Updating rcore_drm.c to only use one api for input
* Change RPI log prefix to DRM
* Remove relative checking which is not supported currently
* Loop should continue on invalid event in drm backend
* Fixed and cleaned up PollKeyboardEvents() in drm backend
* Added gamepad rumble to rcore_desktop.c and rcore_desktop_sdl.c
Still need to add to the rest of the platforms.
* Add SetGamepadVibration warnings to unimplemented platforms.
* Added MAX_GAMEPAD_VIBRATION_TIME
The rumble in SDL2 will continue for MAX_GAMEPAD_VIBRATION_TIME unless the user cancels it with a call to SetGamepadVibration(0.0f,0.0f,0.0f)
* Cast float duration value to Uint 32
* Changed defines from int to float and fixed typo
