AGGhas been around for a very long time, is highly tested, and once you code up the basic integration issues a huge world of completely awesome 2d software rendering falls out fairly easily (gaussian blur, vector shape rendering, textured lines, etc. etc.)I was previously unaware of this project; thanks for the link. It looks quite impressive. It appears that AGG does not have a function to do what Ian was asking for though - transforming a rectangle to an arbitrary quadrilateral. What it can do, though, is transform a rectange to an arbitrary parallelogram.
Seems like some folks (Fredrik Lundh among them) have made some agg wrappers for python:
