`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.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
