CompositeSprite LocalPosition Bug
This fixes a bug with the CompositeSprite. When setting the local
position of a sprite within a CompositeSprite the SpatialDirty flag
needs to be set to true for the Sprite to be redrawn at the new
position. The occurs when the CompositeSprite is moving, rotating, or
if the CompositeSprite automatically changes size because of the sprite
relocation. However, if the CompositeSprite is still, the inner sprite
will not be redrawn at the new location. This change fixes that simply
by setting the SpatialDirty flag to true when the inner sprite is moved.
