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...
