We can't always assume they are NV12. Even if they _are_ NV12,
they may have DRM format modifiers that are incompatible with
simply assuming linear Y and UV buffers (such as tiling).
Right now this renderer works on X11 & Wayland with VAAPI as a backend.
Some rendering latency benchmarks on my `i7-10510U` (with
`intel-media-driver` 20.1.1 which cause a *huge* regression with the
SDL_Renderer):
| | X11 | Wayland |
| Before | 6.78ms | 22.50ms |
| EGLRenderer | 0.76ms | 00.77ms |
