 106   Handle table       gdiObjects
 107   ------------       ----------

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