 102   Handle table       gdiObjects
 103   ------------       ----------

 105   [1]----param2---     wxBrush
 106   [2]             |    wxFont
 107   [3]             | -> wxPen
 108
 109  The handle table works as follows.
 110  When a GDI object is created while reading in the
 111  metafile, the (e.g.) createpen record is added to the
 112  first free entry in the handle table. The createpen
 113  record's param1 is a pointer to the actual wxPen, and
 114  its param2 is the index into the gdiObjects list, which only
 115  grows and never shrinks (unlike the handle table.)
 116
 117  When SelectObject(index) is found, the index in the file
 118  refers to the position in the handle table. BUT we then
 119  set param2 to be the position of the wxPen in gdiObjects,
 120  i.e. to param2 of the CreatePen record, itself found in
 121  the handle table.
 122
 123  When an object is deleted, the entry in the handletable is
 124  NULLed but the gdiObjects entry is not removed (no point, and
 125  allows us to create all GDI objects in advance of playing the
 126  metafile).
