112 Handle table gdiObjects
113 ------------ ----------
114 [0] wxPen
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).
