* pending terminal update: just mark the relevant
* character cells as INVALID and wait for the
* scheduled full update to sort it out.
*
* I have a suspicion this isn't the _right_ solution.
* An alternative approach would be to have terminal.c
* separately track what _should_ be on the terminal
* screen and what _is_ on the terminal screen, and
* have two completely different types of redraw (one
* for full updates, which syncs the former with the
* terminal itself, and one for WM_PAINT which syncs
* the latter with the former); yet another possibility
* would be to have the Windows front end do what the

* that happens is that this window procedure receives
* WM_SYSCOMMAND / SC_VSCROLL. [1] The default handler for
* that window message starts a subsidiary message loop,
* which continues to run until the user lets go of the
* scrollbar again. All WM_VSCROLL / SB_THUMBTRACK
* messages are generated by the handlers within that
* subsidiary message loop.
*
* So, during that time, _our_ message loop is not
* running, which means toplevel callbacks and timers and
* so forth are not happening, which means that when we
* redraw the window and set a timer to clear the cooldown
* flag 20ms later, that timer never fires, and we aren't
* able to keep redrawing the window.
*
* The 'obvious' answer would be to seize that SYSCOMMAND
* ourselves and inhibit the default handler, so that our
* message loop carries on running. But that would mean
* we'd have to reimplement the whole of the scrollbar
* handler!
*
* So instead we apply a bodge: set a static variable that
* indicates that we're _in_ that sub-loop, and if so,
* decide it's OK to manually call term_update() proper,
* bypassing the timer and cooldown and rate-limiting
* systems completely, whenever we see an SB_THUMBTRACK.
* This shouldn't cause a rate overload, because we're
* only doing it once per UI event!
*
* [1] Actually, there's an extra oddity where SC_HSCROLL
* and SC_VSCROLL have their documented values the wrong
* way round. Many people on the Internet have noticed
* this, e.g. https://stackoverflow.com/q/55528397
