You could use 3 functions, one for each channel, and combine them using 
an average pigment of 3 pigments. That would get you a blurred pigment 
at about 1/3 the speed of a blurred pattern. Using an average pigment 
would probably be faster. The only way I can see to blur a texture is to 
use an average texture or write a patch.

Some work on that has been done, search through the older messages on 
these groups.

I don't see a macro anywhere in that code. Your function is "parsed" 
once, running through the #while() loops, and then executed whenever it 
is called.
