| 2601 | * _then mark them as done_. This may not be accurate: |
| 2602 | * when painting in WM_PAINT context we are restricted |
| 2603 | * to the rectangle which has just been exposed - so if |
| 2604 | * that only covers _part_ of a character cell and the |
| 2605 | * rest of it was already visible, that remainder will |
| 2606 | * not be redrawn at all. Accordingly, we must not |
| 2607 | * paint any character cell in a WM_PAINT context which |
| 2608 | * already has a pending update due to terminal output. |
| 2609 | * The simplest solution to this - and many, many |
| 2610 | * thanks to Hung-Te Lin for working all this out - is |
| 2611 | * not to do any actual painting at _all_ if there's a |
| 2612 | * pending terminal update: just mark the relevant |
| 2613 | * character cells as INVALID and wait for the |
| 2614 | * scheduled full update to sort it out. |

| 2617 | * An alternative approach would be to have terminal.c |
| 2618 | * separately track what _should_ be on the terminal |
| 2619 | * screen and what _is_ on the terminal screen, and |
| 2620 | * have two completely different types of redraw (one |
| 2621 | * for full updates, which syncs the former with the |
| 2622 | * terminal itself, and one for WM_PAINT which syncs |
| 2623 | * the latter with the former); yet another possibility |
| 2624 | * would be to have the Windows front end do what the |
| 2625 | * GTK one already does, and maintain a bitmap of the |
| 2626 | * current terminal appearance so that WM_PAINT becomes |
| 2627 | * completely trivial. However, this should do for now. |
