I agree.

Yes only those elements have to be build (for now):

glupload
gldownload
glimagesink
glfiltercube

see:
http://cgit.freedesktop.org/gstreamer/gst-plugins-gl/tree/gst/gl/gstopengl.c

I have not yet made the stuffs for the other elements regarding OpenGL ES 2.0.
(OpenGL ES 2.0 only uses shaders, even for basic stuffs)
