im finding this featue very useless right now. what i was trying to do was get an image to be overlayed on top of a polygon, and use scissor to cut the image using the vertices from the polygon. 2 problems; 1 - i can only cut a box? i reckon this function should be extended to allow us to input vertices for a "polygon region" that needs to be cut rather than a rectangle region. it'd make it alot more useful.
secondly, we should have it behave like the blend modes where it will only cut out sections from the render after its been set. (anything BEFORE it is drawn as normal) and when we disable it, everything after should draw as normal. this way we'd still have the ability to use it as we currently do (if anyone does, anyway) but it'd be able to do a whole lot more.
