Antonio Ospite 8de96a2fbb geometrictransform: Add a 2D perspective transform plugin
The perspective plugin applies a 2D perspective (also called projective)
transform to the frame buffer.

A perspective transform can be used for instance to perform keystone
correction when playing the content with a video projector.
