Subject: [PATCH] Bug 1696842 - Establish raster roots for more picture
 composite modes. r=gfx-reviewers,lsalzman

Add MixBlend and ComponentTransfer to the picture composite modes that
unconditionally establish a raster root.

All the known bugs with the raster root code have been fixed, so let's
start incrementally enabling raster roots for more picture modes, and
fix any regressions that come from these before making raster roots
the default for all surfaces.
