Mc2pWindowNewHeight c2pWindow#.w,NewHeight.w ; Change height of already defined c2p object

Once a c2pWindow object has been created you are allowed to alter the operation
height any number of times without having to recreate the entire object.
Information changed in the c2pWindow structure will be affected by the status of
the interlacing features at the time of the object's creation, not the current
settings.
