GstGLFramebuffer

A GstGLFramebuffer represents and holds an OpenGL framebuffer object with it's associated attachments.

A GstGLFramebuffer can be created with gst_gl_framebuffer_new or gst_gl_framebuffer_new_with_default_depth and bound with gst_gl_framebuffer_bind. Other resources can be bound with gst_gl_framebuffer_attach

Note: OpenGL framebuffers are not shareable resources so cannot be used between multiple OpenGL contexts.
