Hi,

I'm trying to adapt the LSystem class used in the Pentigree example to create a fractal plant based on this example:
http://en.wikipedia.org/wiki/L-system#Example_8:_Fractal_plant

Problem is, when I tried implementing these two rules, I very quickly hit the limit of the matrix stack (only 32, apparently).

Is there some way to increase the size of the matrix stack?  Or if not, is there a way I could access the current matrix so that I can store it in my own data structure, and then clear and reapply it myself later?  Building my own stack would be easy but I don't see a way to dump the matrix contents to another variable, and I'd rather not rebuild all of the transform and rotation functions.

Awesome, thanks!
