Remember me mentioning the color matrix feature of GDI+

Experimenting and playing with the feature has given me some really good 
insight.

Talks about conversion to the CIE XYZ colorspace. The numbers in the 
matrix were strange and mysterious to me. (Not only that, but uhg to do 
the conversion I have to use matrix arithmetic. I used to hate doing 
matrix multiplication simply because I'd get confused. I know, I know.) 
anyway ... onward.

Those mystery numbers are actually the values that determine the make up 
of the resulting channels so, in the example of XYZ -> RGB R is actually 
made up of 0.412453 X, 0.357580 Y, 0.180423 Z ... its actually really 
simple!

You can also do weird things with color matricies such as rotate the 
colors along an axis, etc ... much as you can do with points. You can 
also, of course use these matricies to convert a color from one RGB 
profile to another (i.e. from sGRB to AdobeRGB) I'm considering taking a 
close look at rotation to see what I can do, I'm thinking along the 
right axis you can do hue and saturation shifts. :D
