Most coordinate calculations are done with the new inline function
int Fl_Scalable_Graphics_Driver::floor(int coord)
that is used by both the Windows and X11 platforms.
The issue lies in details how floating point scaled coordinates are converted
to integer values and its impact on the drawing of large SVG images.
This commit fixes the X11 platform.
The macOS platform is immune because drawing uses floating point
coordinates.
The Windows platform still needs fixing.
- 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.
Also, define an FLTK event triggered when the scaling is changed and an option
to disable the transient window showing the new scaling factor.

This example code shows how to subclass Fl_Surface_Device and Fl_Graphics_Driver to
endow FLTK with a new kind of graphics output.

Graphics drivers now use up to 6 virtual member functions to support Fl_Image
drawing in the context of GUI and image rescaling :
virtual void draw_pixmap(Fl_Pixmap *pxm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_bitmap(Fl_Bitmap *bm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_rgb(Fl_RGB_Image *rgb, int XP, int YP, int WP, int HP, int cx, int cy)
and
virtual void draw_fixed(Fl_Pixmap *pxm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_fixed(Fl_Bitmap *bm, int XP, int YP, int WP, int HP, int cx, int cy)
virtual void draw_fixed(Fl_RGB_Image *rgb, int XP, int YP, int WP, int HP, int cx, int cy)

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.
