Chris Dalton b832ce61ee Add a path renderer that uses GPU tessellation 
Implements a simple first pass for a path renderer that uses the
classic Red Book "stencil then cover" method, and linearizes curves
with GPU tessellation shaders.

The new path renderer is disabled by default, and can only be enabled
in the viewer UI or by passing the "--pr gtess" flag.
