2370 * paint any character cell in a WM_PAINT context which

2372 * The simplest solution to this - and many, many
2373 * thanks to Hung-Te Lin for working all this out - is
2374 * not to do any actual painting at _all_ if there's a

2380 * An alternative approach would be to have terminal.c
2381 * separately track what _should_ be on the terminal
2382 * screen and what _is_ on the terminal screen, and
2383 * have two completely different types of redraw (one
2384 * for full updates, which syncs the former with the
2385 * terminal itself, and one for WM_PAINT which syncs
2386 * the latter with the former); yet another possibility
2387 * would be to have the Windows front end do what the
2388 * GTK one already does, and maintain a bitmap of the
2389 * current terminal appearance so that WM_PAINT becomes
2390 * completely trivial. However, this should do for now.
