Correct...

Didn't know about this one, I salvaged the code from the Liquid Spray 
include when I needed it...

Correct. Maybe a call it "matrix2"?

Yes...but unless these macros are included with the standard includes, 
people have to copy them into their scene files, which wastes space and 
is not as clear as a new transform would be. Also, think of the use of 
scale, rotate, etc. in little code snippets...missing macros have caused 
people trouble already. And these transforms seem pretty basic...as 
basic as scale, translate, and rotate, at least, and there is already a 
vector function for the axis-rotation...
At the least, I am going to add functions to the source to do these 
transforms(the ones not already implemented, that is)...I have found 
some of them useful in my patches.

Probably not even enough to notice unless you have a loop that does them 
thousands of times.

Yep.
