It's pretty close, but there are minor differences that may make consolidation 
difficult..  Font blending is a single static source color with the alpha 
channel provided in the font bitmap, the position sliders are generated from 
the first column of an image, the edit slider is generated like the normal 
sliders, but with multiple images, etc, etc...
