Hit Testing Flags

The following hit testing flags were introduced in QuickTime 3. These flags are for use with SpriteMediaHitTestAllSprites and SpriteMediaHitTestOneSprite :

spriteHitTestInvisibleSprites , which you set if you want invisible sprites to be hit tested along with visible ones.
spriteHitTestLocInDisplayCoordinates , which you set if the hit testing point is in display coordinates instead of local sprite track coordinates.
spriteHitTestIsClick , which you set if you want the hit testing operation to pass a click on to the codec currently rendering the sprites image. For example, this can be used to make the Ripple codec ripple.
