ccpr: Calculate edge coverage in the coverage processor

Does the opposite-edge coverage calculation for curves in the coverage
processor, rather than the Shader class. This allows the vertex shader
implementation to do it more clean and directly, as well as allowing
the future sample mask implementation to disregard edge coverage
entirely.
