It has been done as a macro. There are three transforms I am 
considering: 

axis_rotate AMOUNT, AXIS  Rotates around a specified axis.

directional_scale AMOUNT, DIRECTION  Scales in a certain direction(like 
in the LiquidSpray include and the particle_stretch feature in my 
particle_system patch).

coordinate_system X, Y, Z  Takes three vectors for the new directions of 
each axis. This would make operations like shearing a lot easier.

These could all be done with macros, but might be nice if available 
built-in. Rotate, scale, and translate could also be done as macros(and 
maybe they would have been if macros had existed at the beginning), all 
that is really necessary is the matrix transform.
