305 * Clips the start and end points to a rectangle.

314 * This derivation is based on the comments in X.org's xserver/mi/mizerclip.c,

318 * For x major lines we have 2dy >= err + bias > 2dy - 2dx
319 * 0 >= err + bias - 2dy > -2dx
321 * Note dx, dy, m and n are all +ve.
323 * Moving the start pt from x1 to x1 + m, we need to figure out y1 + n.

330 * n = ceiling((2mdy + bias - dx) / 2dx)
331 * = (2mdy + bias + dx - 1) / 2dx (assuming division truncation)
333 * Moving start pt from y1 to y1 + n we need to figure out x1 + m - there may be several

335 * 0 >= 2mdy - 2ndx + bias - dx > -2dx

339 * m = (2ndx - bias - dx) / 2dy + 1
341 * Moving end pt from x2 to x2 - m, we need to figure out y2 - n
342 * err = 2dy - dx + 2(dx - m)dy - 2(dy - n)dx
343 * = 2dy - dx - 2mdy + 2ndx
344 * 0 >= 2dy - dx - 2mdy + 2ndx + bias - 2dy > -2dx
345 * 0 >= 2ndx - 2mdy + bias - dx > -2dx
346 * again exactly one solution.
347 * 2ndx <= 2mdy - bias + dx
348 * n = floor((2mdy - bias + dx) / 2dx)
349 * = (2mdy - bias + dx) / 2dx
351 * Moving end pt from y2 to y2 - n when need x2 - m this time maximizing x2 - m so
352 * mininizing m to include all of the points at y = y2 - n. As above:
353 * 0 >= 2ndx - 2mdy + bias - dx > -2dx
354 * 2mdy >= 2ndx + bias - dx
355 * m = ceiling((2ndx + bias - dx) / 2dy)
356 * = (2ndx + bias - dx - 1) / 2dy + 1
