Currently it seems that integration of user GL code
w/ RegionRenderer and RenderState is poorly supported,
sorry about that!

A workaround would be to use
  RenderState.setShaderProgram(final GL2ES2 gl, final ShaderProgram spNext) {..}
which will notify the RenderState about the ShaderProgram switch.

We shall have an API entry either to simply flush RenderState's
current state or add a flag to _force_ the 'setShaderProgram(..)' switch.

Maybe both will be beneficially.

Would you be so kind to add a bug report w/ this knowledge?
In case you like to make this change yourself, pls go ahead
and offer a git patch (mail, your-repo/branch, ..) w/ a small unit test.

Great to see graph gets adopted!

Thank you!
