MCludgeCookie ShapeNumber.w,Memory.l ; Cludge shape's cookie from existing mem

Once a chunky Shape object has been created you may wish to cludge a new cookie
from some existing graphics memory rather than create a new memory area for it.
This command allows you to do that, although bear in mind that it uses the
following expression to calculate where the cookie should begin:
Base=((Memory+16) and $FFFFFFF0). This is to provide proper support for block and
tile routies on 040+ cpu's so be careful that you have reserved at least 16 bytes
more memory than is needed to hold the entire cookie.
