This adds a utility function that can determine if a given point intersects an arbitrary polygon, by counting how many edges a "semi-infinite" horizontal ray crosses from that point. The plan is to use this for a software based read-pixel fast path that avoids using the GPU to rasterize journaled primitives and can instead intersect a point being read with quads in the journal to determine the correct color. |
