My first OpenGL shader! Momma will be so proud!
This shader implements the software renderer mask semantics where the source pixel is multiplied by the color and alpha modulation values and then any pixel with non-zero alpha is fully opaque.
The OpenGL renderer on Mac OS X now passes all the automated render tests! :)
