- remove obsolete svn '$Id$' tags from all source files
- update .fl files and generated files accordingly
- replace 'http://www.fltk.org' URL's with 'https://...'
- replace bug report URL 'str.php' with 'bugs.php'
- remove trailing whitespace
- fix other whitespace errors flagged by Git
- add and/or fix missing or wrong standard headers
- convert tabs to spaces in all source files
The only relevant code changes are in the fluid/ folder where
some .fl files and other source files were used to generate
the '$Id' headers and footers.
Each image has now two sizes implemented as follows:
- the pixel size is stored in private members pixel_w_ and pixel_h_
with public accessors pixel_w() and pixel_h()
- the FLTK size is stored in private members w_ and h_ and read by w() and h()
- when the image is constructed, the two sizes have the same value
- the protected w(int) and h(int) member functions set both FLTK and pixel sizes.
- the public scale(int, int) member function is essentially nothing but
set the FLTK size and don't change the pixel size.
- when the image is drawn, its FLTK size determines how big it is drawn, its pixel
size determines how much data are available to draw it.
FLTK 1.3.4 with FL_ABI_VERSION=10304 contained an equivalent member function
but only for the Fl_Shared_Image class.

Corresponds to STR #3320
1) HiDPI support consists in detecting the adequate scaling factor for the screen on which
FLTK maps a window, and scaling all FLTK units by this factor. FLTK tries to detect the correct
value of this factor at startup (see more details below). Environment variable
FLTK_SCALING_FACTOR can also be used to set this value.
2) Rescaling support consists in changing the scaling factor of all FLTK windows
in reply to ctrl/+/-/0/ keystrokes.
More details for the various platforms :
- X11: Support is very advanced. Some details need still to be improved.
Automatic detection of the correct starting value of the scaling factor works well
with the gnome desktop. The present code contains no support for this on
other desktops. FLTK_SCALING_FACTOR provides a workaround.
-WIN32: Support is incomplete at this point, although many test
applications have partial or complete HiDPI and scaling support.
The current value of the system's scaling factor is correctly detected
at application startup. Apps respond to changes of this value in real time.
Support needs to define the FLTK_HIDPI_SUPPORT preprocessor variable
at compile time. This way, standard builds produce a code with the
default WIN32 HiDPI support, that is, where all graphics goes to an internal
buffer that gets enlarged by the system and then mapped to the HiDPI
display. To experiment with (or develop) the new HiDPI support requires
a modified build procedure in which FLTK_HIDPI_SUPPORT is defined
at compile time. When the support will be complete, the requirement for the
definition of this preprocessor variable will be removed. The present commit
contains support for a single scaling factor. Eventually, per-screen scaling
factors should be implemented, as done for X11.
- MacOS: this commit does not give new HiDPI for this platform.
Eventually, window rescaling in reply to command/+/-/0/ is desirable.
Per-screen scaling factor makes no sense on this platform because
the OS itself takes care of the difference between the resolutions of
traditional and retina displays.

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.

the fltk_images library; saves about 16k in the FLTK core library on my
Intel system.
Fix a memory leak bug in most of the fl_set_fonts*.cxx implementations;
as a result, the Fl_Fontdesc structure now has a fontname member to old
the human-readable font name.
Lots of fixes for shadowed variables, etc.
Use snprintf, strlcpy, and strlcat in more places.
