Don't treat transforms with rotation or skew as having invalid scale

We can calculate quite accurate scale for any transform without
perspective using gfx::ComputeTransform2dScaleComponents(), so we
can stop treating rotation and skew as having invalid scale, to make
raster scale for animations containing such transform operations
more accurate.
