John Stiles 351b86128a Simplify Porter-Duff coefficient blending expression. 
The earlier implementation generated a very very long expression on a
single line. I split out the logic across into multiple lines, and
also realized that the majority of the logic was repeated two times. Now
we use a vec2 to avoid spelling out the math twice.
