1433 * Some fonts, e.g. 9-pt Courier, draw their underlines

1436 * we lose the underline completely. Here we try to work
1437 * out whether this is such a font, and if it is, we set a
1438 * flag that causes underlines to be drawn by hand.
1440 * Having tried other more sophisticated approaches (such
1441 * as examining the TEXTMETRIC structure or requesting the
1442 * height of a string), I think we'll do this the brute
1443 * force way: we create a small bitmap, draw an underlined
1444 * space on it, and test to see whether any pixels are
1445 * foreground-coloured. (Since we expect the underline to
1446 * go all the way across the character cell, we only search
1447 * down a single column of the bitmap, half way across.)

2498 * when painting in WM_PAINT context we are restricted

2500 * that only covers _part_ of a character cell and the
2501 * rest of it was already visible, that remainder will
2502 * not be redrawn at all. Accordingly, we must not
2503 * paint any character cell in a WM_PAINT context which
2504 * already has a pending update due to terminal output.
2505 * The simplest solution to this - and many, many
2506 * thanks to Hung-Te Lin for working all this out - is
2507 * not to do any actual painting at _all_ if there's a
2508 * pending terminal update: just mark the relevant
2509 * character cells as INVALID and wait for the
2510 * scheduled full update to sort it out.
2512 * I have a suspicion this isn't the _right_ solution.
2513 * An alternative approach would be to have terminal.c
2514 * separately track what _should_ be on the terminal
2515 * screen and what _is_ on the terminal screen, and
2516 * have two completely different types of redraw (one
2517 * for full updates, which syncs the former with the
2518 * terminal itself, and one for WM_PAINT which syncs
2519 * the latter with the former); yet another possibility
2520 * would be to have the Windows front end do what the
2521 * GTK one already does, and maintain a bitmap of the
2522 * current terminal appearance so that WM_PAINT becomes
2523 * completely trivial. However, this should do for now.
