Implement Angle for Desktop and iOS.

[MAJigsaw77]

This PR adds support for Google’s Almost Native Graphics Layer Engine (ANGLE) on desktop platforms and iOS, allowing OpenGL ES to be translated to modern graphics backends such as Vulkan and Metal.

The graphics APIs used across the libraries are configured as follows:

• Windows / Linux -> Vulkan
• macOS / iOS -> Metal

If you’re wondering “What about Android?”: some manufacturers already use ANGLE at the system level, which means no additional changes are required on our side for Android support.

Why was Vulkan chosen for Windows instead of Direct3D?

Why was Vulkan chosen for Windows instead of Direct3D?

Performance and texture compression reasons, since vulkan can load ASTC but dx11 cant.

Aswell as vulkan supports advanced blend modes but dx11 cant

Now in case theres no Vulkan drivers, it'll fallback to DirectX11.

Now in case theres no Vulkan drivers, it'll fallback to DirectX11.

I suggest making the fallback to OpenGL aswell, as DirectX11 has messy implementation and poor performance in my tests.

Show a comparison between the two.

sure thing, I have OpenGL builds for ANGLE that I use as default.

I dont really see much of a diff, from the first video with DirectX11 it acually seems to go to 62 fps.

High FPS is meaningless if the game experiences lag spikes or/and black-box rendering issues.

And also in WINE, DirectX11 repeatedly logs "Ignoring" messages, which isn’t ideal.

Fair enough then

I found an issue with Vulkan on Intel integrated GPUs (Intel UHD, i5-12450H).
Screen is completely black, render is not working.
Maybe it's specific to my hardware, but wanted to report it.

I'll offer my temporary fix as a solution - lime-nmb - commit

I also have i5-12450H with Intel UHD Graphics but never encountered this issue in Vulkan nor OpenGL besides black-boxes in DirectX11 of course. Might be a driver problem.

Maybe my driver is outdated. I’ll check it and let you know what happens.

I updated the driver from version 31 to version 32, but I still get a black screen. The issue seems to be specific to Intel CPUs.
