/* Attempt at an inheritance diagram.
/* Inheritance diagram.
+- Fl_Surface_Device: any kind of surface that we can draw onto -> uses an Fl_Graphics_Driver
|
+- Fl_Display_Device: some kind of video device
+- Fl_Copy_Surface: create an image for dnd or copy/paste
+- Fl_Image_Surface: create an RGB Image
+- Fl_Paged_Device: output to a printer or similar
+- Fl_Display_Device: some kind of video device (one object per app)
+- Fl_Widget_Surface: any FLTK widget can be drawn to it
|
+- Fl_..._Surface_: platform specific driver
+- Fl_Printer: user can instantiate this to gain access to a printer
+- Fl_System_Printer:
+- Fl_PostScript_File_Device
+- Fl_Copy_Surface: draw into the clipboard (in vectorial form if the platform supports it)
+- Fl_Copy_Surface_Driver: helper class interfacing FLTK with draw-to-clipboard operations
|
+- Fl_PostScript_Printer
+- Fl_..._Copy_Surface_Driver: platform-specific implementation of Fl_Copy_Surface_Driver
+- Fl_Image_Surface: draw into an RGB Image
+- Fl_Image_Surface_Driver: helper class interfacing FLTK with draw-to-image operations
|
+- Fl_..._Image_Surface_Driver: platform-specific implementation of Fl_Image_Surface_Driver
+- Fl_Paged_Device: output to a page-structured surface
|
+- Fl_Printer: user can instantiate this to gain access to a printer
+- Fl_..._Printer_Driver: platform-specific helper class interfacing FLTK with print operations
+- Fl_PostScript_File_Device: draw into a PostScript file
|
+- Fl_Posix_Printer_Driver: Fl_Printer uses that under Posix platforms
+- Fl_Graphics_Driver
+- Fl_Graphics_Driver -> directed to an Fl_Surface_Device object
|
+- Fl_..._Graphics_Driver: platform specific graphics driver
+- Fl_PostScript_Graphics_Driver: platform-independent graphics driver for PostScript drawing
+- Fl_..._Graphics_Driver: platform-specific graphics driver (MacOS, Android, Pico)
+- Fl_Quartz_Printer_Graphics_Driver: MacOS-specific, for drawing to printers
+- Fl_Scalable_Graphics_Driver: helper class to support GUI scaling
+- Fl_Xlib_Graphics_Driver: X11-specific graphics driver
+- Fl_GDI_Graphics_Driver: Windows-specific graphics driver
+- Fl_GDI_Printer_Graphics_Driver: re-implements a few member functions especially for output to printer
+- Fl_OpenGL_Graphics_Driver: draw to an Fl_Gl_Window (only very partial implementation)
