stambaughw d96039a1fb Change search path order, wxDC zoom updates, and code clean ups. 
Add helpers for inserting paths to and removing paths from search list.
Moved user defined path before default library paths in search list.
Renamed m_Draw_Auxiliary_Axis to DrawAuxiliaryAxis.
Changed parameter to fix wxDC set mode from FALSE to GR_COPY.
Minor wxDC zoom improvements.
