Properly handle alpha in fg color when rendering symbolic icons
@alexl
Submitted by Alexander Larsson Link to original bug (#734668)
Description
You don't really want to just re-render the icon with a color with alpha, but rather you want to apply the alpha as a group. That way the alpha applies to other colors too, handles overlapped draws of the fg color, and allows the prerendered pngs symbolics to work.
