A stripped down version yes (currently it has some fbo stuff and some sink
specific stuff).

GstGLMemory + GstGLBufferpool.

GstGLMemory holds one rgba texture id.  It also allows non-GL elements to read
and write to a data pointer that is up/downloaded as needed.  Where the element
wants the image data and whether it needs up/downloading is based on the map
flags _READ, _WRITE and _GL.
