Dan Glastonbury 7811112058 Bug 1465307 - P1: Extend StyleComplexColor to support additive blending. r=hiro,xidorn
Refactored StyleComplexColor to support "complex" blending between
background (numeric) color and foreground color (currentColor).
Made explicit the distinction between numeric, currentColor and a
complex blend in Gecko and Stylo.

This is to support SMIL animation, for example, of the form:

     <animate from="rgb(10,20,30)" by="currentColor" ... />
