x11 video playback is broken

[jdm]

Not sure where to comment about this. I'll just bring a comment I put in the branch:

I have just tested the old implementation (x11/raw frames) and it doesn't work anymore. Perhaps the surfman change produced a regression?

And I can't enable WebGL in Linux/Wayland now with surfman (i knew how to enable it in the old offscreen-rendering-context, but not anymore :/).

@ceyusa Can you be more specific? Are you talking about video playback in general not working in the non-GL case, or video with GL playback, or the video being used as a webgl texture?

[ceyusa]

Yes, sorry.

I meant that (simple360Player)[https://github.com/gbentaieb/simple360Player] is not working on X11 with no GL rendering on the player (raw frames), which was working when I implemented the get_image_pixles() for video.
