PhIntersectTilings()

Determine the intersection of two lists of tiles

Synopsis:

PhTile_t *PhIntersectTilings( 
             PhTile_t const * const tile1,
             PhTile_t const * const tile2,
             unsigned short *num_intersect_tiles );

Description:

This function creates a new list of tiles that's the intersection of the lists pointed to by tile1 and tile2. The original lists aren't modified.

Returns:

A pointer to the new list, or NULL if there's no intersection.

Note:

Don't free() the list of tiles; instead, use PhFreeTiles() to return the tiles to the internal pool.
