2. reorganized wxImageList a bit, created a new wxInvertMask() function 3. an incredibly ugly fix (?) for "unsatisfied constraints" warnings 4. added wxIcon and wxBitmap ctors from XPM 5. XPM handler now creates bitmaps with mask 6. added wxPrinterDC::BitBlt() and DrawBitmap(), cleared the horrible mess in the wxDC methods with the same names git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@5571 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
