Is this ever getting GPU acceleration?

See also LigGPU and LibSoftGPU in the same folder.
If it'll ever get GPU support, I'd expect it to be based on QEMU/libvirt GPU acceleration rather than any direct hardware support.
Unless someone knowledgeable and motivated enough has a crack at it and writes a driver forttheir GPU, of course That's an immense task, though, so I wouldn't expect it any time soon. Maybe an Intel engineer will get bored or something.
