GBM/KMS platform

[i509VCB]

It may be useful to allow presenting CPU rendered buffers directly to the display on Linux.

raw-window-handle already supports GBM and DRM so it should be possible to use GBM or dumb buffers.

DRM support could be neat, if it was also supported in winit or something else (I guess allowing only a single window, and using libinput for input events?).

Are there currently any crates that provide RawWindowHandles for DRM?

winit work for that is underway, see rust-windowing/winit#2272
