Thank you. I think that some of the sorts of changes you had in your patch have actually been made in the interim. I now have a branch with a few small changes that I think may be all that is necessary for full support of variable alpha in colormaps. I will turn it into a pull request shortly, after a bit more testing and inclusion of an example, assuming I don't run into a major problem along the way.
