Joshua Ashton d2e27b0a8c glamor: Don't glFlush/ctx switch unless any work has been performed 
`glamor_make_current` is always called before any calls to GL.

Apply some dirty-tracking to whenever we call `glamor_make_current` so
that we can avoid a decent amount of redundant GL work on each
Dispatch cycle.

Gamescope previously was waking up an empty Xwayland server with an
XQueryPointer and I noticed a significant amount of churn doing
redundant GL work.

This has been addressed on the Gamescope side as well, but avoiding any
useless GL context switches and flushes when glamor is doing nothing
is still beneficial for CPU and power usage on portable devices.
