PIL Image transform

[Dean Card]

Okay, so here is the situation.  I have need to do some on-the-fly image 
creation.  I have everything working great except for the last part of it, 
applying a perspective type transform to the image.  The transform will take 
a rectangular 2D image and transform it to a 3D representation in 2D.

Please see the link to see what I am trying to do:

I have PIL v1.15 installed which has a PERSPECTIVE transform, but it does 
not appear to do what I want - or I can't figure out how to use it correctly 
because it is using a transform matrix's coefficients.

Here is the only info I could find on the usage:

This is for the creation of images to be used in Flash.  Originally I was 
doing the image processing in Flash because Flash 8 has a BitmapData class 
which does the basics of images, copy, transform, etc.  To accomplish the 
transform I was using an algorithm that approximated triangles to fill and 
worked really well, but I need the image processing to be server side, not 
client.

So, here I am.  Anyone have any idea how to accomplish my goal here?  Is 
there a way to fill a triangle with a bitmap using PIL?  What about better 
docs on the PERSPECTIVE transform?

Thanks for any and all help on this.
