I want to implement an IFS system in jitter. I suspect that someone has
already done this. If so, point me the way. If not, some hints. I
understand the process. What I need to do is perform the following

x = ax+by+e
y = cx+dy+f

Where x and y are the coordinates of points and a-f are coefficients that
contain translation, rotation and scaling information. It is a matrix
multiplication.
