OpenGL: edge overlay shaders
As seen at #bcon16. These were produced quickly and probably need further work.
SIMPLE variant draws triangle mesh edges. Based on this research:

http://developer.download.nvidia.com/SDK/10/direct3d/Source/SolidWireframe/Doc/SolidWireframe.pdf
Non-SIMPLE variant can adjust thickness per edge. This can be used to draw only some edges, or accentuate some edges. Given the right inputs this is a general n-gon perimeter shader.
