16 Returns non-zero if point (x, y) lies inside the bitmap. If `clip' is
17 non-zero, the function compares the coordinates with the clipping rec‐
18 tangle, that is it returns non-zero if the point lies inside the clip‐
19 ping rectangle or if clipping is disabled for the bitmap. If `clip' is
20 zero, the function compares the coordinates with the actual dimensions
21 of the bitmap.
