[PATCH 0/5] MR8734: win32u: Use surfaceless EGL platform for nulldrv and create drawables.

[Rémi Bernon (＠rbernon)]

Allows OpenGL to start being used with nulldrv, as long as EGL and this extension are available. Right now it doesn't render to anything though, but we'll later make it use the window surface emulation with FBOs as it gets introduced, (itself a requirement to hook OpenGL rendering for compositing).
