 114   Handle table       gdiObjects

 117   [1]----param2---     wxBrush
 118   [2]             |    wxFont
 119   [3]             | -> wxPen
 120
 121  The handle table works as follows.
 122  When a GDI object is created whilst reading in the
 123  metafile, the (e.g.) createpen record is added to the
 124  first free entry in the handle table. The createpen
 125  record's param1 is a pointer to the actual wxPen, and
 126  its param2 is the index into the gdiObjects list, which only
 127  grows and never shrinks (unlike the handle table.)
 128
 129  When SelectObject(index) is found, the index in the file
 130  refers to the position in the handle table. BUT we then
 131  set param2 to be the position of the wxPen in gdiObjects,
 132  i.e. to param2 of the CreatePen record, itself found in
 133  the handle table.
 134
 135  When an object is deleted, the entry in the handletable is
 136  NULLed but the gdiObjects entry is not removed (no point, and
 137  allows us to create all GDI objects in advance of playing the
 138  metafile).
