Dominik Honnef b183774063 internal/stroke, gpu: reuse slice when splitting cubics ...

When building GPU vertices from paths, we call stroke.SplitCubic once
per OpCubic. Before this change, each call to stroke.SplitCubic would
allocate a slice, which we would only use to iterate over.

This allocation can be easily avoided by reusing the slice. We can
conveniently store it in gpu.quadSplitter.

In a real application that renders hundreds of paths with tens of
rounded rectangles per path, this saved roughly 4500 allocations (or 1
MB worth) per frame.
