Rewrote the OpenGL object rendering to indexed triangle / quad sets

Browse source 
for lower memory consumption.
Rewrote the print path 3D preview to generate these indexed triangle / quad
sets, possibly with at least as possible duplication of vertices,
with a crease angle of 45 degrees, leading to maximum 8% overshoots
at the corners.
