2375 * when painting in WM_PAINT context we are restricted

2380 * paint any character cell in a WM_PAINT context which
2381 * already has a pending update due to terminal output.
2382 * The simplest solution to this - and many, many
2383 * thanks to Hung-Te Lin for working all this out - is
2384 * not to do any actual painting at _all_ if there's a
2385 * pending terminal update: just mark the relevant
2386 * character cells as INVALID and wait for the
2387 * scheduled full update to sort it out.

2390 * An alternative approach would be to have terminal.c
2391 * separately track what _should_ be on the terminal
2392 * screen and what _is_ on the terminal screen, and
2393 * have two completely different types of redraw (one
2394 * for full updates, which syncs the former with the
2395 * terminal itself, and one for WM_PAINT which syncs
2396 * the latter with the former); yet another possibility
2397 * would be to have the Windows front end do what the
2398 * GTK one already does, and maintain a bitmap of the
2399 * current terminal appearance so that WM_PAINT becomes
2400 * completely trivial. However, this should do for now.
