  I started writing some (non-Qgis) python code yesterday to experiment 
with raster renderings. I use numpy arrays to store a single band of 
raster data, and a new class to simulate multi-band rasters. Then I 
wrote some RasterRenderer classes (single-band grayscale, three-band 
RGB, single band unique colour lookup) and I can view them with the 
matplotlib.pylab functions.

  Its a handy way to do rapid development and experiment with raster 
renderer interfaces. I'll probably make the code available sometime.
