-// This path renderer is made to create geometry (i.e. primitives) from the original path (before
-// the path is stroked) and render using the GPU directly rather than using any software rendering
-// step. It can be rendered in a single pass for simple cases and use multiple passes for features
-// like AA or opacity support.
