fltk/FL/Fl_Pixmap.H
Manolo Gouy 8e3f66073f 1) Added a new way to detect whether the drawing operation is using the platform's native driver
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.
