persp_shaders_ gm expected diff (in gpu backends only), due to change
from filterquality (which gpu and cpu interpreted differently for mips)
to samplingoptions (which both backends interpret the same).
Specifically for kMedium:
- gpu treated as SkMipmapMode::kLinear
- cpu treated as SkMipmapMode::kNearest
