Bill, you repeatedly dismiss a central concept of cairo which is:
one input => multiple output

Your suggestion is about one font sort for Xlib, one other for Quartz, 
32-bit Floating point here, only half there and there only double or 
integers. Such would be all workarounds.

What the colour management thread here is about to propose a clearly 
useable API, which integrates well with the style of typical 
unaltered input used for cairo for different output. If I have to sort 
every input for the appropriate backend, then possibly more dedicated 
libraries are better useable.

kind regards
