Subject: [PATCH] The line clipping function is quite useful, so I made it
 public. Sometimes it's handy to work out where your line was/would be drawn.

int
imlib_clip_line(int x0, int y0, int x1, int y1, int xmin, int xmax, int ymin,
                  int ymax, int *clip_x0, int *clip_y0, int *clip_x1,
                  int *clip_y1);
