Detailed Description

This bench exercises the GPU backend's Rectanizer classes. It exercises the following rectanizers: Pow2 Rectanizer Skyline Rectanizer in the following cases: random rects (e.g., pull-save-layers forward use case) random power of two rects small constant sized power of 2 rects (e.g., glyph cache use case)
