All GPU APIs except OpenGL ES 2 can generate mipmaps for textures.
This trades 33% more GPU memory use for improved rendering quality
and speed for downscaled images.

This change implements support for compute programs in the Direct3D 11
driver. The compute renderer doesn't work for me yet; my NVIDIA GTX 970
and Intel GPUs both display corrupted output and hangs.

Modern API such as Metal and Vulkan want clients to compile expensive
state changes into pipeline objects. Change our GPU driver abstraction
to match, thereby paving the way for future drivers.

We're about the merge the Direct3D backend into package gpu. Extract the
raw Direct3D API to its own package, just like package glimpl.
