Improve quality of mesh and material resource previews in the editor

Browse Source 
This uses a combination of MSAA and SSAA to make thumbnails smoother
while also improving texture sampling quality. Thumbnail generation time
is largely unaffected since most of the time is spent doing things
on the CPU anyway, and the thumbnail resolution is still 128×128
(although the 3D buffer is internally 256×256 now).
