Add custom window background/clear color (incl. transparency) support, fixes #272
wgpu would currently ignore the alpha: https://github.com/gfx-rs/wgpu/issues/687
glow (and naively patched wgpu) requires premultiplied alpha, so if you don't
multiply the RGB by the A right now, the semi-transparent color would be wrong
(too bright).
winit with_transparent doesn't seem necessary.
