(float, float) (x, y)
  clipPoint (float, float) (x, y)
         to (float, float, float, float) (x1, y1, w1, h1);

Adjust the point to lie within the rectangle.

(float, float)
  clipLine (float, float) (x1, l1)
        to (float, float) (x2, l2);

Return that part of the first line that has all its points in common with the second line. Both lines start at x and run for l `pixels'.

(float, float, float, float)
  clipRect (float, float, float, float) (x1, y1, w1, h1)
        to (float, float, float, float) (x2, y2, w2, h2);

Return that part of the first rectangle that lies within the second rectangle.

boolean
        rect (float, float, float, float) (x1, y1, w1, h1)
  intersects (float, float, float, float) (x2, y2, w2, h2);

Return TRUE iff there is at least one point common to both argument rectangles.

(float, float, float, float)
  unionRect (float, float, float, float) (x1, y1, w1, h1)
       with (float, float, float, float) (x2, y2, w2, h2);

Return the rectangle enclosing just both argument rectangles. If either rectangle has a zero width or height, the other rectangle is returned.

boolean
   point (float, float) (p_x, p_y)
  inRect (float, float, float, float) (x, y, w, h);

Return TRUE iff the point (p_x, p_y) lies within the rectangle described by (x, y, w, h).
