* loop, we'd get nothing but NETEVENTs if the server
* flooded us with data, and stop responding to any other
* kind of window message. So instead, we keep on round
* this loop until we've consumed at least one message
* that _isn't_ a NETEVENT, or run out of messages
* completely (whichever comes first). And we don't go to
* run_toplevel_callbacks (which is where the netevents
* are actually processed, causing fresh NETEVENT messages
* to appear) until we've done this.

* when painting in WM_PAINT context we are restricted
* to the rectangle which has just been exposed - so if
* that only covers _part_ of a character cell and the
* rest of it was already visible, that remainder will
* not be redrawn at all. Accordingly, we must not
* paint any character cell in a WM_PAINT context which
* already has a pending update due to terminal output.
* The simplest solution to this - and many, many
* thanks to Hung-Te Lin for working all this out - is
* not to do any actual painting at _all_ if there's a
* 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
* GTK one already does, and maintain a bitmap of the
* current terminal appearance so that WM_PAINT becomes
* completely trivial. However, this should do for now.
