[ODE] graphics front end

Well, ODE doesn't need fancy graphics, but at least we
could try to make drawstuff faster for simulations.

The test_moving_trimesh.exe sample runs slower with
bunnies: the reason isn't the trimesh code (It runs
fast now!), but certainly the code for drawing
trimeshes is too slow. Indeed, the drawing code uses 
glBegin-glVertex-glEnd like commands for drawing each
triangle. If the bunny has about 1000 triangles, have
you idea how slower it would be?

At least, we can paste some code for drawing Trimeshes
with vertex array instead.
