Cycles: optimization for 3D viewport border render with heavy scenes, the OpenGL

render of objects could slow things down when redrawing the view each time a new
sample is displayed.

Now it does a partial redraw of the viewport with only the render border area,
skipping OpenGL object drawing while the render is refining.
