AGG
has 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:

http://tachyon.in/davinci/
The latter one is part of a larger package. Fredrik's includes an api
to do affine transforms.
