1447 * foreground-coloured. (Since we expect the underline to

2500 * when painting in WM_PAINT context we are restricted

2502 * that only covers _part_ of a character cell and the
2503 * rest of it was already visible, that remainder will
2504 * not be redrawn at all. Accordingly, we must not
2505 * paint any character cell in a WM_PAINT context which
2506 * already has a pending update due to terminal output.
2507 * The simplest solution to this - and many, many
2508 * thanks to Hung-Te Lin for working all this out - is
2509 * not to do any actual painting at _all_ if there's a
2510 * pending terminal update: just mark the relevant
2511 * character cells as INVALID and wait for the
2512 * scheduled full update to sort it out.
2514 * I have a suspicion this isn't the _right_ solution.
2515 * An alternative approach would be to have terminal.c
2516 * separately track what _should_ be on the terminal
2517 * screen and what _is_ on the terminal screen, and
2518 * have two completely different types of redraw (one
2519 * for full updates, which syncs the former with the
2520 * terminal itself, and one for WM_PAINT which syncs
2521 * the latter with the former); yet another possibility
2522 * would be to have the Windows front end do what the
2523 * GTK one already does, and maintain a bitmap of the
2524 * current terminal appearance so that WM_PAINT becomes
2525 * completely trivial. However, this should do for now.
