Detailed Description

This bench measures the rendering time of the call SkCanvas::drawPatch with different types of input patches (regular case, with loops, a square, with a big difference between "parallel" sides). This bench also tests the different combination of optional parameters for the function (passing texture coordinates and colors, only textures coordinates, only colors or none). Finally, it applies a scale to test if the size affects the rendering time.
