Detailed Description

This bench draws a grid of either rects or filled paths, with two alternating color patterns. This color patterns are passed in as enums to the class. The options are: 1) solid white color 2) solid blue color 3) opaque bitmap 4) partial alpha bitmap The same color pattern can be set for both arguments to create a uniform pattern on all draws.

The bench is used to test a few things. First it can test any optimizations made for a specific color pattern (for example drawing an opaque bitmap versus one with partial alpha). Also it can be used to test the cost of program switching and/or GrDrawOp combining when alternating between different patterns when on the gpu.
