- * 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.
