Don't adjust raster scale differently for SW/GPU during Animation

Don't adjust raster scale differently for SW/GPU

When GPU raster was initially enabled, we caused GPU raster to
adjust raster scale during animations, re-rastering each animation frame
at its native resolution. While this is theoretically higher quality,
this causes GPU raster to do significantly more work than SW in these
cases. As downscaling has produced acceptable quality for SW, this
change causes GPU to match SW's behavior, improving GPU raster
performance in these cases.
