SYNTAX
int VG3_coll_check(struct vg3_coll_ret *collret, struct vg3_rect *rect1from, struct vg3_rect *rect1to, struct vg3_rect *rect2)

FUNCTION PARAMETERS
collret For returning collision-return values
rect1from Begin position of the moving object-instance
rect1to End position of the moving object-instance
rect2 Position of the second object-instance

RETURN VALUE
Returns integer: - 0: Collision detected - 1: No collision detected

DESCRIPTION
Check if an object-instance, while it is moving from a begin position to an end position, represented by two rectangles, collides with another given static object-instance. The common way to check for collsion in a quadtree is VG3_coll_q_find().
