The screen grabber was a workaround for an extremely slow path in Mesa when reading back pixel data from the frame buffer. It was using pixel buffer objects by directly calling into GL to hit a fast blit path in Intel's driver. This should no longer be necessary with the latest Mesa because the normal read pixels path now has a fast path to just memcpy the data. Using PBOs in that case just adds an extra indirection because the data is read into an intermediate buffer and then copied back out again. We want to be able to remove the dependency on linking against libGL directly from Gnome Shell because that will not work if Cogl is actually using GLES. Also libGL includes GLX which means gnome-shell ends up with a hard dependency on Xlib which hinders the goal of getting Gnome Shell to be a Wayland compositor. https://bugs.freedesktop.org/show_bug.cgi?id=46631 https://bugzilla.gnome.org/show_bug.cgi?id=685915
