| * clip_line |
| * |
| * Clips the start and end points to a rectangle. |

| * point is clipped out, then the likelihood is that the new end point |
| * should be displayed. |
| * |
| * Returns 0 if totally excluded, 1 if partially clipped and 2 if unclipped. |
| * |
| * This derivation is based on the comments in X.org's xserver/mi/mizerclip.c, |
| * however the Bresenham error term is defined differently so the equations |
| * will also differ. |
| * |
| * For x major lines we have 2dy >= err + bias > 2dy - 2dx |
| * 0 >= err + bias - 2dy > -2dx |
| * |
| * Note dx, dy, m and n are all +ve. |
| * |
| * Moving the start pt from x1 to x1 + m, we need to figure out y1 + n. |

| * 0 >= 2dy - dx + 2mdy - 2ndx + bias - 2dy > -2dx |
| * 0 >= 2mdy - 2ndx + bias - dx > -2dx |
| * which of course will give exactly one solution for n, |
| * so looking at the >= inequality |
| * n >= (2mdy + bias - dx) / 2dx |
| * n = ceiling((2mdy + bias - dx) / 2dx) |
| * = (2mdy + bias + dx - 1) / 2dx (assuming division truncation) |
| * |
| * Moving start pt from y1 to y1 + n we need to figure out x1 + m - there may be several |
| * solutions we pick the one that minimizes m (ie that first unlipped pt). As above: |
| * 0 >= 2mdy - 2ndx + bias - dx > -2dx |
| * 2mdy > 2ndx - bias - dx |
| * m > (2ndx - bias - dx) / 2dy |
| * m = floor((2ndx - bias - dx) / 2dy) + 1 |
| * m = (2ndx - bias - dx) / 2dy + 1 |
| * |
| * Moving end pt from x2 to x2 - m, we need to figure out y2 - n |
| * err = 2dy - dx + 2(dx - m)dy - 2(dy - n)dx |
| * = 2dy - dx - 2mdy + 2ndx |
| * 0 >= 2dy - dx - 2mdy + 2ndx + bias - 2dy > -2dx |
| * 0 >= 2ndx - 2mdy + bias - dx > -2dx |
| * again exactly one solution. |
| * 2ndx <= 2mdy - bias + dx |
| * n = floor((2mdy - bias + dx) / 2dx) |
| * = (2mdy - bias + dx) / 2dx |
| * |
| * Moving end pt from y2 to y2 - n when need x2 - m this time maximizing x2 - m so |
| * mininizing m to include all of the points at y = y2 - n. As above: |
| * 0 >= 2ndx - 2mdy + bias - dx > -2dx |
| * 2mdy >= 2ndx + bias - dx |
| * m = ceiling((2ndx + bias - dx) / 2dy) |
| * = (2ndx + bias - dx - 1) / 2dy + 1 |
| * |
| * For y major lines, symmetry (dx <-> dy and swap the cases over) gives: |
| * |
| * Moving start point from y1 to y1 + n find x1 + m |
| * m = (2ndx + bias + dy - 1) / 2dy |
| * |
| * Moving start point from x1 to x1 + m find y1 + n |
| * n = (2mdy - bias - dy) / 2ndx + 1 |
