Revert "Avoid drawing BW clipped color glyphs many times."

This reverts commit bba38ee80e4140908ac0c351dc18a2f1224e5f0a.

Reason for revert: possibly breaking chrome text

Original change's description:
> Avoid drawing BW clipped color glyphs many times.
> 
> Prior to this change if a color glyph is drawn through the raster device
> with an aliased clip the glyph is drawn once for each rectangular region
> in the aliased clip. In addition, even when the glyph was not a color
> glyph in this situation, the mask was checked for being a color glyph
> once for each rectangular region of the aliased clip. This change hoists
> the test for the color format out of the loop to ensure that the mask
> format is checked once and the mask is drawn once.
> 
> This issue was discovered by rotating the coloremoji_blendmodes gm.
