Added HRTF (Kemar) samples for 3d spatialization Exposed frame buffer width and height for camera renderFrame calls. Fixed a bug that caused objects containing a mixture of both opaque and transparent materials to be rendered entirely in the transparent render pass. Now the sub meshes are evaluated independently.
