| * 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. |
