New Revision: 27281
   Changeset: http://svn.mythtv.org/trac/changeset/27281


Don't call QGLContext::doneCurrent() in MythRenderOpenGL.

- it should be unnecessary given that makeCurrent always checks the
correct context is current to the current thread and following the
threading changes, all of our OpenGL usage should be in the same thread.
- it breaks playback on certain Windows builds.
- it has a sizeable performance impact on at least one system tested
(Intel GPU)

Based on a patch from Lawrence Rust.
