godot-angle-static/src/libANGLE/Caps.cpp
Corentin Wallez 3d677ea685 Implement EGL_ANGLE_x11_visual 
Reland with a fixed tests on AMD.

This extension will be used by Chrome to advertise the visual it will
use for its windows. Having ANGLE use the same visual will bring
several benefits:
 - A blit will be avoided, and the content of the window might be
   rendered on the system framebuffer directly.
 - There will be less latency when resizing windows which will make it
   much less likely to see a black border when resizing.
