Just pass color glyph masks to filters.

Allow the filters to try to apply themselves to the color mask. Most
mask filters will just return false, but allow them the opprotunity.
This removes the behavior of trying to create a mask from the color
mask.

This updates the blur mask filter to handle kARGB32_Format directly by
using just the alpha (which mirrors current behavior).
