/**
* 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.
