  * fix-polygon-behaviour-64
  Fixed issue 'Strange polygon behaviour on 64-bit machines'
  reported by Chris Mears at 14 Dec 2006.
    =

  Problem: the arrays inspected by the wxDC_Polygon function
  are assumed to contain 32-bits ints. On 64-bit machines
  these are actually 64-bits ints.
    =

  Fix: (a bit of a hack...) the code now assumes that the
  arrays contain intptr_t values. This type represents ints
  of the same number of bits as the Haskell ints (on 32-bit
  and 64-bit machines). The code now dereferences each element
  in the array correctly, but still truncates the possibly
  64-bit value to a 32-bit value. This is not a problem
  in practice.
