2511 * We have to be careful about term_paint(). It will
2512 * set a bunch of character cells to INVALID and then
2513 * call do_paint(), which will redraw those cells and
2514 * _then mark them as done_. This may not be accurate:
2515 * when painting in WM_PAINT context we are restricted
2516 * to the rectangle which has just been exposed - so if
2517 * that only covers _part_ of a character cell and the
2518 * rest of it was already visible, that remainder will
2519 * not be redrawn at all. Accordingly, we must not
2520 * paint any character cell in a WM_PAINT context which
2521 * already has a pending update due to terminal output.
2522 * The simplest solution to this - and many, many
2523 * thanks to Hung-Te Lin for working all this out - is
2524 * not to do any actual painting at _all_ if there's a
2525 * pending terminal update: just mark the relevant
2526 * character cells as INVALID and wait for the
2527 * scheduled full update to sort it out.
2529 * I have a suspicion this isn't the _right_ solution.
2530 * An alternative approach would be to have terminal.c
2531 * separately track what _should_ be on the terminal
2532 * screen and what _is_ on the terminal screen, and
2533 * have two completely different types of redraw (one
2534 * for full updates, which syncs the former with the
2535 * terminal itself, and one for WM_PAINT which syncs
2536 * the latter with the former); yet another possibility
2537 * would be to have the Windows front end do what the
2538 * GTK one already does, and maintain a bitmap of the
2539 * current terminal appearance so that WM_PAINT becomes
2540 * completely trivial. However, this should do for now.

4959 * I always thought pasting was synchronous in Windows; the
4960 * clipboard access functions certainly _look_ synchronous,
4961 * unlike the X ones. But in fact it seems that in some
4962 * situations the contents of the clipboard might not be
4963 * immediately available, and the clipboard-reading functions
4964 * may block. This leads to trouble if the application
4965 * delivering the clipboard data has to get hold of it by -
4966 * for example - talking over a network connection which is
4967 * forwarded through this very PuTTY.
4969 * Hence, we spawn a subthread to read the clipboard, and do
4970 * our paste when it's finished. The thread will send a
4971 * message back to our main window when it terminates, and
4972 * that tells us it's OK to paste.
