Because of the large number of changes I have made, I am including the 
whole files instead of listing the changes. However, I have also been 
working on some other stuff...if you see something about "blur_matrix", 
just ignore it. I think I weeded all of that stuff out, though. The 
stuff relevant to the transform patch is pretty clearly identifiable.

This patch does two things:
1: it allows transform {...} blocks to be placed in objects, textures, 
etc. There might be a problem with media densities, though, that portion 
of the code doesn't seem to make any sense. It may be a bug.
Anyway, this means you can do things like this:
object {
    transform {
        transform identifier, rotate, translate, scale, etc...
The old syntax of "transform TRANSFORM_IDENTIFIER" is still supported.

2: it allows transforms to be inverted with the "inverse" keyword. Like 
object {
    transform {Trans}
    transform {Trans inverse}// this reverses the above transform
