8863ef7901 Avoid multiple definition of macro __fl_attr() 
This could happen if both FL/fl_ask.H and fluid/Fl_Type.h were
included in the same file.

3ee8864bfc Simplify and fix the code of Fl_Scroll::bbox() 
Declare Fl_Scroll::bbox() and Fl_Scroll::recalc_scrollbars() 'const'.
These methods don't change the Fl_Scroll widget.

Use Fl_Scroll::recalc_scrollbars() in Fl_Scroll::bbox() to simplify
the code and to avoid code duplication.

bbox() can now be called at any time and returns the correct values,
no matter if draw() has been called before.

(old constructor) is discouraged (deprecated).

6ac305a508 Remove compiler warnings '-Wextra-semi' (see also PR #266) 
I compiled with `-Wextra-semi -Werror=extra-semi` on Linux and Windows
(cross-compiled on Linux) and removed all "extra semicolon" warnings
I could find. I didn't check on macOS (yet).

Note: Linux configured with and w/o Pango but not w/o Xft. Compilation
with other options (e.g. Cairo) might still emit such warnings.

9abbff2078 Add virtual int Fl_Group::delete_child(int n) (STR 3218) 
This is a convenience method that does range checking (index n),
removes the child given by index n from the group and deletes it.

08a8e78d6e Fix compiler warning 
Apple clang version 12.0.5 (clang-1205.0.22.9)

Warning appeared after upgrade to Xcode 12.5 in several files,
example:

In file included from Fl_Scroll.cxx:19:

231159e16c Fix for issue #155 - continued 
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.

Pango ps (#148) 
Use cairo-PostScript to output PostScript when pango is available.

This allows to draw in vectorial form any script.
Before, only the Latin script could be drawn to PostScript in vectorial form.
