Julian Smart a91b47e800 Solved wxMotif scrolling display problem; added wxImageModule;
added wxRETAINED support in wxMotif; changed wxDC::SetBackground behaviour;
changed OnKeyDown/OnChar behaviour; fixed wxToolBar toggle bugs; fixed
wxImage on wxMotif bug whereby new was used to allocate XImage data
