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.

cf20474d7c CMake: Simplify adding test programs for developers 
The intention is to make it more convenient for developers to add
one or more test programs for their tests by editing only one
variable (extra_tests).

cc82b742be Improve GIF error handling, terminate on some errors 
There's not much we can do if we find unknown data in the main
parser loop. The best we can do is terminating.

If we find a GIF trailer (0x3b) this means logical end of file.
If we get there in the main loop the GIF file is empty (no image).

This behavior is consistent with many other image viewers including
browsers (Firefox and Chrome).

b6a69db9a6 Rename 'fileno()' method to 'get_fileno()' for MinGW 
See fltk.coredev thread "fltk-1.4 fluid build broken on 32-bit mingw"
https://groups.google.com/g/fltkcoredev/c/W9LWbsNuGZg/m/MW1BVAkeAgAJ

This regression was introduced in commit c8c1f51db7 in an
attempt to fix a Visual Studio (MSVC) warning but broke "old" MinGW
builds that define 'fileno' as a macro.

bc0d18c1bb Enable error and EOF check in class Fl_Image_Reader (#271) 
This is part 1 and a prerequisite for the fix of issue #271.
It enables the user of this internal class (Fl_{BMP|GIF}_Image)
to test for read errors and EOF (end of file) while reading.

The method used to read data from memory got an optional third
argument 'const long datasize = -1)' to limit the size of the
memory block of data provided to the image reader. Default is -1
which means "unlimited" (backwards compatibility).

Using only two arguments (w/o size limit) is deprecated and should
only be done if the data size is not available.

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.
