2511 * paint any character cell in a WM_PAINT context which
2512 * already has a pending update due to terminal output.
2513 * The simplest solution to this - and many, many
2514 * thanks to Hung-Te Lin for working all this out - is
2515 * not to do any actual painting at _all_ if there's a
2516 * pending terminal update: just mark the relevant
2517 * character cells as INVALID and wait for the
2518 * scheduled full update to sort it out.
2520 * I have a suspicion this isn't the _right_ solution.
2521 * An alternative approach would be to have terminal.c
2522 * separately track what _should_ be on the terminal
2523 * screen and what _is_ on the terminal screen, and
2524 * have two completely different types of redraw (one
2525 * for full updates, which syncs the former with the
2526 * terminal itself, and one for WM_PAINT which syncs
2527 * the latter with the former); yet another possibility
2528 * would be to have the Windows front end do what the
2529 * GTK one already does, and maintain a bitmap of the
2530 * current terminal appearance so that WM_PAINT becomes
2531 * completely trivial. However, this should do for now.
