publicuseColliderShape
Use any existing Collider component geometry for pointer events. This is useful if you want
user pointer events only to trigger on the same collision geometry used in the collider component
for collision resolution. Default is true.
publicuseGraphicsBounds
Use any existing Graphics component bounds for pointers. This is useful if you want the axis aligned
bounds around the graphic to trigger pointer events. Default is true.
