Summary: Triangle subdivide option

Initial Comment:
I noticed when a triangle face is subdivded, the 
current implementation finds the midpoints of the 
triangle sides, and connects the midpoints together.  
I have an idea for a different way of dividing up a 
triangle that might be better for some uses.  Not as a 
replacement for the current way, but if the user could 
choose between the two ways it would be nice.

Instead of connecting the midpoints to each other, 
connect each midpoint to a new vertex at the center
(median) of the triangle.  When this is done you end 
up with three quadrilateral faces.  The fact that this 
creates a new vertex in the center seems like it could 
be more useful for shaping an object, just like a 
quadrilateral sudivision yields a vertex in the center.
Here is an example...
      ^
     / \
    / 1 \
   /\   /\
  /  \ /  \
 / 2  |  3 \
/_____|_____\

Aternatively, the corners of the triangle could be 
connected in addition to the midpoints, making six 
triangles from one, but that is probably going too far
(and the ascii art gets a little ridiculous ;-) ).
      ^
     /|\
    /1|2\
   /\ | /\
  /3 \|/ 4\
 /__-/|\-_ \
//_5__|_6__\

Oops, the forum program automatically deleted most of the spaces on my diagrams.  Oh well, the idea isn't too complicated, hopefully I explained it well enough.

I've even been thinking about trying to implement this feature myself through hacking the source, but I'm still having been some trouble getting the original code to compile.  Maybe I'll figure it out in a few days, when I have the time...
