Adds aSpriteSetMember to the sprite set. Panics if a null member is passed in, or if the argument does not include a bitmap and mask.

Creates and returns a pointer to a CSpriteSet object clipped to the parent aWindow. The sprite set is initialized with aSpriteSetMember and the sprite set takes ownership of this parameter. aWs is the window session used. aInvertMask specifies whether the bitmap/mask pairs which will be added will use an inverted mask.

Prepares the sprite in the set of type aSpriteType to be displayed at aSpritePos with size aSpriteSize. The sprite will be resized as necessary under the restriction of aSpriteResizeMode.

Removes a member (indexed by aSpriteSetMemberIndex) from the array. Panics if the member index is not within the existing array's range.

Bounds the drawing of the sprite within aRect, stopping it drawing over surrounding components.

Allows use of the Gc which the sprite uses for it's drawing. This enables the client to effectively draw onto the sprite.
