Re: Reducing GL context switches

Hi, Martin

With our GPU-proxy/thread/process, I hope we can eliminate that code, but for now, it should be there to reduce context switch.

Thanks

Henry

I've updated one of my patches in the branch with the following change:
The commit "gl: Intelligently release the context" no longer makes the
previous GL context current when releasing a GL device. Instead, if the
previous GL context was the same as the one controlled by the GL device,
releasing will not call glXMakeCurrent/eglMakeCurrent.

I haven't heard any objections to these patches for months, so I plan on
committing them, if no one objects to the new branch.
