 112   Handle table       gdiObjects

 115   [1]----param2---     wxBrush
 116   [2]             |    wxFont
 117   [3]             | -> wxPen
 118
 119  The handle table works as follows.
 120  When a GDI object is created whilst reading in the
 121  metafile, the (e.g.) createpen record is added to the
 122  first free entry in the handle table. The createpen
 123  record's param1 is a pointer to the actual wxPen, and
 124  its param2 is the index into the gdiObjects list, which only
 125  grows and never shrinks (unlike the handle table.)
 126
 127  When SelectObject(index) is found, the index in the file
 128  refers to the position in the handle table. BUT we then
 129  set param2 to be the position of the wxPen in gdiObjects,
 130  i.e. to param2 of the CreatePen record, itself found in
 131  the handle table.
 132
 133  When an object is deleted, the entry in the handletable is
 134  NULLed but the gdiObjects entry is not removed (no point, and
 135  allows us to create all GDI objects in advance of playing the
 136  metafile).
