-----------
3D Viewport rendering (Blender Internal)
Added incremental re-render on view changes. That means all data preprocessing
only needs to be done once on view changes, quite faster that way.
Also fixed a bug in raytracing strands with soft shadows, was wrongly changing
coordinates in a static array.
Note: proper signals for re-renders is still on the todo. Many button options
don't signal a re-render yet. Work around: press G+ESC for quick full renders.
