and whether we are printing: virtual int Fl_Graphics_Driver::has_feature(driver_feature feature) This is also because it is not convenient to derive a printer-specific driver with its own implementation of virtual functions when this implementation differs only in one line of code. 2) Solved the problem of inclusion of non public header by the public header FL/Fl_Device.H: bracket this with #if FL_LIBRARY / #endif so this non public header is included only when building FLTK itself. 3) Removed several (but not all) of the FLTK_ABI_VERSION guards that are no longer useful for code targeting FLTK 1.4. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3-porting@11063 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
