double *  y0,
double *  x1,
double *  y1,
double  xmin_,
double  xmax_,
double  ymin_,
double  ymax_

cohen_sutherland_line_clip_d: : x coordinate of first point. : y coordinate of first point. : x coordinate of second point. : y coordinate of second point. : x coordinate of lower left edge of clipping rectangle. : y coordinate of lower left edge of clipping rectangle. : x coordinate of upper right edge of clipping rectangle. : y coordinate of lower left edge of clipping rectangle.

cohen_sutherland_line_clip_d() will clip a line from first point (, ) to (, ) so that it fits into the given min/max bounds of the rectange (, ) - (, ). The line input coordinates will be modified if necessary for clipping.

Returns: ClipResult.
