# Since this program can't necessarily handle events as fast as the X
# server can generate them, it's important to use some sort of `flow
# control' to throw out excess events when we're behind.
# For pointer motion events, this is accomplished by selecting
# PointerMotionHint on the slider (see above), so that the server
# never sends a sequence of motion events -- instead, it sends one,
# which we throw away but use as our cue to query the pointer
# position. The query_pointer is then a sign to the server that we'd
# be willing to accept one more event, and so on. Notice that this
# requires several round trips between the server and the client for
# each motion, which in C programs is a source of performance
# problems, but here the difference is lost in the noise (we also do a
# round trip to calculate the width of the text when updating the
# progress bar, which could be done on the client side the way Xlib
# does).
# Expose and ConfigureNotify (resize) events have the same problem,
# though it's only noticeable if your window manager supports opaque
# window movement or opaque resize, respectively (the latter is fairly
# rare in X, perhaps because average X clients handle it fairly
# poorly; I for one am quite envious of how smoothly windows resize in
# Windows NT). We can't do anything to tell the server to only send us
# one of these events, but the next best thing is to just ignore them
# until there aren't any other events pending. (In some toolkits this
# would be called `idle-loop' processing). It's always safe to ignore
# intermediate resizes, but with expose events we can only do this
# because we always redraw the whole window, instead of just the
# newly-visible part. A more sophisticated approach would keep track
# of the exposed region, either with a bounding box or some more
# precise data structure, and then clip the drawing to that (either
# client-side or using a clip mask in the GC). Of course, that almost
# certainly wouldn't be a speed win, because it would be doing a lot
# of work in perl to save a few iterations of highly optimized C in
# the server.
