API
Use a custom display driver in the IPR
This addition allows third-parties to use a custom display driver for rendering or in an IPR session to display the render in an external viwer (e.g. Aton).
Separate override flags in the Instancer API
This change makes the usage of shape overrides (e.g. visibility, opaque, etc.) of the Instancer API more cleaner.
