Remove OSMesa support ( #905 )
...
Mesa has now removed OSMesa from its codebase, see
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33836
There is no reason to keep this any longer, especially since EGL can do
the same and more.

Render3D: Huge refactor that adds the new Render3DColorOut class, which now handles the framebuffers that integrate the 3D layer and the BG0 layer.
...
- Framebuffers are now double-buffered, which may help improve performance on games running at less than 60 FPS on host systems with weak GPUs.
- For OpenGL, slightly improve framebuffer download performance on macOS.

posix: in __glx_initOpenGL, add null check after XOpenDisplay ( #920 )
...
* posix: in `__glx_initOpenGL`, add null check after `XOpenDisplay`
Would segfault when built with GLX enabled and ran in Wayland. Now the same scenario instead falls back to the SoftRasterizer. Still not ideal, but using SDL as a fallback requires considerably more code redesign.
* posix: refine GLX with no X server error message

- Fix a bug where max bright down would display a red screen instead of a black screen when running in 18-bit or 24-bit color mode.
- Fix incorrect colors for various display capture scenarios.
- 15-bit to 18-bit and 15-bit to 24-bit color conversions now assume byte swapping. This improves 2D graphics performance by up to 5%.

Partially revert commit 0367d14. Looks like the algorithm for converting RGBA6665 to RGBA5551 colors in AltiVec doesn't need to be THAT accurate, so resimplify the algorithm again to pick up the speed.

...
- The main Xcode project disables Metal API Validation for Debug builds, since this seems to cause runtime issues on Xcode 16.
- The Xcode 3 project removes the git lookup build script for the PowerPC LLVM-Clang build, since the typical use case for this particular build won't have git commands available.

2b40a2f12c
Take another pass at silencing a bunch of compiler warnings where appropriate.
...
Most warnings are related to the following:
- Integer precision loss from implicit conversion
- Non-virtual destructors for classes with virtual methods
- Replace the unsafe sprintf() function with the safer snprintf()
- Local variables shadowing
- Extraneous commas and semicolons
Not all of these warnings have been fixed yet,, since fixing the remaining warnings requires a deeper review of the code for a proper fix.

rename FASTCALL to DESMUME_FASTCALL
...
mingw's winnt.h uses FASTCALL for its own purposes, so depending on
the include order the code uses either mingw's definition, or the
one from types.h. that makes it almost impossible to reason which
definition ends up being used, even though it's of utmost importance
to have the jit perform correctly.
