* consistency tweak
* unified color and depth buffer
* tweaks
* review the storage of clear values + complete get/set depth value
* copy/blit fast path
* better simd read/write
* framebuffer alignment
* fix 'typo'
my french slipped out
* simplified framebuffer management
* convert texture to rgba32
* remove float copy/blit
* adding SIMD framebuffer read/write
This adds SIMD framebuffer read/write, and also texel fetch.
This supports SSE2/SSE41 and SISD fallback (also includes ARM NEON support, conceptually identical but still needs testing).
* consistency
* tweaks
* review of `sw_texture_sample_linear`
* better quad sorting
unrelated to the PR, but at least it's done
* ignore some pipeline state in certains context
* convention tweaks

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.

* 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.

- make sure that src/external/rl_gputex.h uses it's own macros
for printing warnings and allocating memory
- add few additional macros in order to decouple rl_gputex from headers
that are being included by Raylib (e.g. *_MEMSET, *_NULL and so on)
- make sure that rl_gputex uses RL_*ALLOC, TRACELOG and RLAPI macros
when (and only when) being included by src/rtextures.c
- replace LOG() and RL_GPUTEX_SHOW_LOG_INFO macros with: RL_GPUTEX_WARN
and RL_GPUTEX_SHOW_WARN_INFO (this is a breaking change, but it was
broken and unusable anyway, see:
https://github.com/raysan5/raylib/issues/5039#issuecomment-3065732596 )
- fixes issue all issues mentioned in:
https://github.com/raysan5/raylib/issues/5039#issuecomment-3065732596
- remove logging upon successfully saving a file; Raylib does this
anyway and we want rl_gputex to only print WARNings upon failures;
see: https://discord.com/channels/426912293134270465/541710686468702250/1394406734306480352
- add additional condition when saving a file; now checks for both
fwrite() and fclose() failures; before it would warn about both,
but only return result based on fclose()
- add some notes about the current state of compiling rl_gputex
without depending on Raylib (spoiler: it's still broken...)
- bump rl_gputex version to 1.1 since this is a potential breaking
change (only for people attempting to use it without Raylib)
Fixes: https://github.com/raysan5/raylib/issues/5039
Reference: https://discord.com/channels/426912293134270465/541710686468702250/1394403611852931255
I did this with the intention of fixing
https://github.com/raysan5/raylib/issues/5027
but it's hard to tell if it will help in that case or not.
Anyway, bumping the header with mappings should be done once in a while.
I haven't found any Raylib script for doing this, so here's how I did it
step-by-step with CMake rule provided by GLFW (I'm on Linux, but this
should be similar on any other POSIX system):
```sh
$ git clone https://github.com/raysan5/raylib.git
$ cd raylib/src/external/glfw/
$ cmake -B ./build -DGLFW_BUILD_EXAMPLES=OFF -DGLFW_BUILD_TESTS=OFF -DGLFW_BUILD_DOCS=OFF -G "Unix Makefiles"
$ make -C ./build update_mappings
$ rm -fr ./build
```
then I checked, if any mappings were deleted (without updating) with
following shell one-liner:
```sh
# you must be at 'raylib/src/external/glfw/' when executing this
$ for i in $(git diff ./src/mappings.h | sed -n -e 's/^-"\([0-9a-z]*\),.*$/\1/p'); do grep <./src/mappings.h "$i" > /dev/null || echo "$i"; done;
```
which gave me the following IDs:
```txt
0300000066f700000500000000000000
030000000d0f00001600000000007803
03000000efbe0000edfe000000000000
03000000786901006e70000000000000
050000005e040000e002000030110000
03000000790000000600000010010000
030000000d0f00000d00000000010000
030000000d0f0000d800000072056800
03000000c0160000dc27000001010000
030000008916000000fd000024010000
```
I have checked all those IDs with `git log -p` against
https://github.com/mdqinc/SDL_GameControllerDB
and it seems that all of them were deleted by upstream (I was afraid that
maybe some mappings were added manually by a Raylib contributor and then
overwritten by my patch, but they weren't; All good!)
Undefine DEBUG to avoid external redefinition
warnings/conflicts. This is probably a common
definition for many external build systems'
debug configurations.
This ensures raylib will not emit
a warning about the DEBUG definition being
redefined in external build systems.
