done.  the cairo change now uses a double for color tolerance, while 
pixman retains the enum. 
_cairo_color_tolerance_to_pixman_color_tolerance now maps 0.0 => LOW, 
(0.0,0.5) => MEDIUM, [0.5,1.0] => HIGH.  0.0 is the default.

I've also finally figured out enough git to put my changes up in 
accessible git repos:
