Detailed Description

implements offscreen rendering

vr_kit derives from gl_vr_display to provide offscreen rendering vor openvr driver as well as for the vr_emulated_kit of the vr_emulator. Implements the init_fbos(), enable_fbos(), disable_fbos(), destruct_fbos() and blit_fbo() functions with opengl and glew only.
