Use SkCanvas::SkCanvas(SkBitmap) instead of going thru SkSurface
I learnt that you can just wrap an SkBitmap with an SkCanvas for cases
like these. SkSurface is a more general thing when your backing may
not be in cpu memory or when you have more complicated SkImageInfo.
For us, it is coming from the SkBitmap which is cpu memory-backed. So
this is simpler code.
