To be honest, I think the gst1-plugins-base/Config.in handling of
OpenGL support is completely over-engineered, and whenever we get
patches like this one, or http://patchwork.ozlabs.org/patch/1143636/, I
have the feeling of adding more and more layers of ducktape on
something that is already severely broken.

Can we revisit the handling of OpenGL support in
gst1-plugins-base/Config.in to make it more sane ?
