2502 * thanks to Hung-Te Lin for working all this out - is
2503 * not to do any actual painting at _all_ if there's a
2504 * pending terminal update: just mark the relevant
2505 * character cells as INVALID and wait for the
2506 * scheduled full update to sort it out.
2508 * I have a suspicion this isn't the _right_ solution.
2509 * An alternative approach would be to have terminal.c
2510 * separately track what _should_ be on the terminal
2511 * screen and what _is_ on the terminal screen, and
2512 * have two completely different types of redraw (one
2513 * for full updates, which syncs the former with the
2514 * terminal itself, and one for WM_PAINT which syncs
2515 * the latter with the former); yet another possibility
2516 * would be to have the Windows front end do what the
2517 * GTK one already does, and maintain a bitmap of the
2518 * current terminal appearance so that WM_PAINT becomes
2519 * completely trivial. However, this should do for now.

4968 * for example - talking over a network connection which is
