It's fully implemented in 1.2 using a simple and fast ray-triangle intersection 
algorithm i borrowed. I think it's also in the current Alpha branch. I did the 
same thing for misc_model selection, although for that I transform the ray into 
object space before doing the intersection test. For both, there isn't any 
noticeable computation overhead in addition to the XY/Cam redraw and the calcs 
already done by the brush-selection process.
