1433 * out whether this is such a font, and if it is, we set a
1434 * flag that causes underlines to be drawn by hand.
1436 * Having tried other more sophisticated approaches (such
1437 * as examining the TEXTMETRIC structure or requesting the
1438 * height of a string), I think we'll do this the brute
1439 * force way: we create a small bitmap, draw an underlined

1441 * foreground-coloured. (Since we expect the underline to
1442 * go all the way across the character cell, we only search

2494 * when painting in WM_PAINT context we are restricted
2495 * to the rectangle which has just been exposed - so if
2496 * that only covers _part_ of a character cell and the
2497 * rest of it was already visible, that remainder will
2498 * not be redrawn at all. Accordingly, we must not
2499 * paint any character cell in a WM_PAINT context which
2500 * already has a pending update due to terminal output.
2501 * The simplest solution to this - and many, many
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.
