Problem: Using abs() requires type cast to int.
Solution: Use labs() so that the value remains long. (Hong Xu)

17 * ScreenLines[off] Contains a copy of the whole screen, as it is currently | |

19 * ScreenAttrs[off] Contains the associated attributes. | |

24 * For double-byte characters, two consecutive bytes in ScreenLines[] can form | |
25 * one character which occupies two display cells. | |

32 * (drawn on top of the first character). There is 0 after the last one used. |
7 | 33 * ScreenLines2[] is only used for euc-jp to store the second byte if the |
34 * first byte is 0x8e (single-width character). | |
35 * | |
36 * The screen_*() functions write to the screen and handle updating | |
37 * ScreenLines[]. | |
38 * | |
39 * update_screen() is the function that updates all windows and status lines. | |
40 * It is called form the main loop when must_redraw is non-zero. It may be | |
1213 | 41 * called from other places when an immediate screen update is needed. |
7 | 42 * |
43 * The part of the buffer that is displayed in a window is set with: | |
44 * - w_topline (first buffer line in window) | |
45 * - w_topfill (filler line above the first line) | |
46 * - w_leftcol (leftmost window cell in window), | |
47 * - w_skipcol (skipped window cells of first line) | |
48 * | |
49 * Commands that only move the cursor around in a window, do not need to take | |
50 * action to update the display. The main loop will check if w_topline is | |
51 * valid and update it (scroll the window) when needed. | |
52 * | |
53 * Commands that scroll a window change w_topline and must call | |
54 * check_cursor() to move the cursor into the visible part of the window, and | |
55 * call redraw_later(VALID) to have the window displayed by update_screen() | |
56 * later. | |
57 * | |
58 * Commands that change text in the buffer must call changed_bytes() or | |
59 * changed_lines() to mark the area that changed and will require updating | |
60 * later. The main loop will call update_screen(), which will update each | |
61 * window that shows the changed buffer. This assumes text above the change | |
62 * can remain displayed as it is. Text after the change may need updating for | |
63 * scrolling, folding and syntax highlighting. | |
64 * | |
65 * Commands that change how a window is displayed (e.g., setting 'list') or | |
66 * invalidate the contents of a window in another way (e.g., change fold | |
67 * settings), must call redraw_later(NOT_VALID) to have the whole window | |
68 * redisplayed by update_screen() later. | |
69 * | |
70 * Commands that change how a buffer is displayed (e.g., setting 'tabstop') | |
71 * must call redraw_curbuf_later(NOT_VALID) to have all the windows for the | |
72 * buffer redisplayed by update_screen() later. | |
73 * | |
743 | 74 * Commands that change highlighting and possibly cause a scroll too must call |
75 * redraw_later(SOME_VALID) to update the whole window but still use scrolling | |
76 * to avoid redrawing everything. But the length of displayed lines must not | |
77 * change, use NOT_VALID then. | |
78 * | |
7 | 79 * Commands that move the window position must call redraw_later(NOT_VALID). |
80 * TODO: should minimize redrawing by scrolling when possible. | |
81 * | |
82 * Commands that change everything (e.g., resizing the screen) must call | |
83 * redraw_all_later(NOT_VALID) or redraw_all_later(CLEAR). | |
84 * | |
85 * Things that are handled indirectly: | |
86 * - When messages scroll the screen up, msg_scrolled will be set and | |
87 * update_screen() called to redraw. | |
