spark: use blitter to scale to non-720p framebuffer resolutions

Browse Source 
Let everyone render in an offscreen buffer of 1280x720 pixels,
then blit to primary, scaling to target resolution.

This will need some calls to ->blit() sprinkled all over neutrino
which will come in a follow-up commit.
