Bug List

Member WT_Layer::set_visibility (WT_Boolean vis)
The layer visibility is neither serialized nor materialized. This option was not part of the original WHIP! spec. Changing at this stage would be prohibitively difficult. Another workaround exists, the layer materialize / serialize code could use the rendition visibility to determine its state; however existing WHIP! data was written assuming that the layer didn't pay attention to the rendition visibility. Were we to start doing so, many legacy drawings would be materialized has having invisible layers, not the author's intention.

Member WT_Object::skip_operand (WT_Opcode const &opcode, WT_File &file)
Not all objects perform skip_operand() correctly; this is a known problem. For best results, if client code must use WT_File::get_next_object_shell() manually, it should also call the corresponding WT_Object::materialize() method to avoid this problem.

WT_File::get_next_object_shell(), WT_File_Heuristics::set_deferred_delete().
