- made a template function for editmesh enthusiasts.

Browse Source 
- goes in a loop,
  - draws current window
  - sets view transform to correct matrix
  - you can draw stuff
  - swapbuffers
  - event queue test to escape

Test: CTRL+R in editmode.
Right now it hilites the closest edge to to mouse cursor, just for fun!
Goofster will use it for the loop-cutter tool later. But the template
will remain there, commented out, for others to play with.
