Add classes Fl_SVG_File_Surface and Fl_EPS_File_Surface to draw to SVG and EPS.

Browse Source 
Test programs device and pixmap_browser use these new classes.
Class Fl_SVG_File_Surface can be optionally made non functional using the
--disable-svg configure option or turning off OPTION_USE_SVG in CMake.
Class Fl_EPS_File_Surface can be optionally made non functional using the
--disable-print configure option or turning off OPTION_PRINT_SUPPORT in CMake.

New Features and Extensions
- (add new items here)
- New classes Fl_SVG_File_Surface and Fl_EPS_File_Surface to save any FLTK
graphics to SVG or EPS files, respectively.
- New fl_putenv() is a cross-platform putenv() wrapper (see docs).
- New Fl::keyboard_screen_scaling(0) call stops recognition of ctrl/+/-/0/
keystrokes as scaling all windows of a screen.

of Fl_Clock, Fl_Clock_Output, and derived widgets.
- New method Fl_Tabs::tab_align() allows to set alignment of tab labels,
particularly to support icons on tab labels (STR #3076).
- Added '--enable-print' option to configure effective under X11 platforms
and with 'yes' default value. Using '--enable-print=no' removes print
and PostScript support from the FLTK library, thus reducing its size.
- Added Fl_Surface_Device::push_current(new_surface) and
Fl_Surface_Device::pop_current() to set/unset the current surface
receiving graphics commands.

New Configuration Options (ABI Version)
- The library can be built without support for SVG images using the
--disable-nanosvg configure option or turning off OPTION_USE_NANOSVG in CMake.
- The library can be built without support for reading SVG images or writing
graphics in SVG format using the --disable-svg configure option
or turning off OPTION_USE_SVG in CMake.
- The library can be built without support for PostScript, thus reducing
its size, using the --disable-print configure option or turning off
OPTION_PRINT_SUPPORT in CMake. That makes classes Fl_PostScript_File_Device,
Fl_EPS_File_Surface and Fl_Printer (under X11 platform only) ineffective.
- FLTK's ABI version can be configured with 'configure' and CMake.
See documentation in README.abi-version.txt.

Other Improvements
- (add new items here)
- Support for building for the arm64 architecture used by macOS 11.0 "Big Sur".
- Add optional argument to Fl_Printer::begin_job() to receive
a string describing the error when an error occurs.
- Fix Windows-specific bug when the program tries to enlarge a
