2424 * set a bunch of character cells to INVALID and then

2426 * _then mark them as done_. This may not be accurate:
2427 * when painting in WM_PAINT context we are restricted
2428 * to the rectangle which has just been exposed - so if
2429 * that only covers _part_ of a character cell and the
2430 * rest of it was already visible, that remainder will
2431 * not be redrawn at all. Accordingly, we must not
2432 * paint any character cell in a WM_PAINT context which
2433 * already has a pending update due to terminal output.
2434 * The simplest solution to this - and many, many
2435 * thanks to Hung-Te Lin for working all this out - is
2436 * not to do any actual painting at _all_ if there's a
2437 * pending terminal update: just mark the relevant
2438 * character cells as INVALID and wait for the
2439 * scheduled full update to sort it out.
2441 * I have a suspicion this isn't the _right_ solution.
2442 * An alternative approach would be to have terminal.c
2443 * separately track what _should_ be on the terminal
2444 * screen and what _is_ on the terminal screen, and
2445 * have two completely different types of redraw (one
2446 * for full updates, which syncs the former with the
2447 * terminal itself, and one for WM_PAINT which syncs
2448 * the latter with the former); yet another possibility
2449 * would be to have the Windows front end do what the
2450 * GTK one already does, and maintain a bitmap of the
2451 * current terminal appearance so that WM_PAINT becomes
2452 * completely trivial. However, this should do for now.
