ARGB edge extrude #247

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
For bilinear scaling it can be useful to have edge pixel RGB values extruded 
onto the transparent pixels, so rendering will filter with the same color.

Suggested implementation
For transparent pixels, do alpha weighted average of 3x3.
Alternatively use RGB of the pixel with highest alpha.

Defer - no immediate need.  Work around by preattenuating art.
