Hi Quinn,

you need to start from the beginning. This is my proposal how you could start:

Get a working tfp code:
Write a small tool that redirects one window with CompositeRedirectAutomatic. 
This will give you the window pixmap with XCompositeNameWindowPixmap that can 
be used for tfp but the window will still be painted on the screen. Then add 
a glx window to this app and try to get the window texture with tfp. You 
should be able to use lot of the glx code of compiz to make it work.

Create a composite manager:
Try to convert xcompmgr to a tfp composite manager with the tfp code that 
worked with the test tool above.
