* CMake integration, no autotiools
* alignment panel is now correctly renamed to setting panel
* source view is now correctly renamed to code view
* Merge FLTK FLUID docs into FLUID user manual.
* Add two simple entry tutorials
* Remove FLUID chapter form FLTK docs.
* GitHub action to generate HTML and PDF docs and
make the available as artefacts
* this commit introduces a few FIXMEs and TODOs that probably
can't be solved until we do some major refactoring. They work for
now, but adding more layout controlling widgets will be hard.
Ctrl-0 is used by FLTK globally to zoom all windows back to 100%,
so FLUID should not override that. Loading the previous file is now
Ctrl-1 instead of Ctrl-0.
* interactive layout alignment rewritten
* interface for new alignment rules
* new alignment dialog box
* user defined layout rules added
* layout rules can be stored in projects, settings, and external files
* Valgrind verification
- add true unittest and Fl_String testing
- interface and printout are similar to gtest
without requiring external linkage.
just run `unittest --core`.
- new Fl_String API
- extended API to fl_input_str and fl_password_str

Removing all globals in file writer (#653 )
Fix some static analyser complaints
Valgrind: handle width==0 in GfxDrivers on Wayland and X11
Don't use `Fl_Input_::static_value`, it accesses previous
buffer that may be deleted
Project file write encapsulated, removing globals
Encapsulating project file reader, removing states in glbals
Project i/o increased source code readability
* Full support o when()
* Making undo suspend nesting
* Finally correct undo handling for Label: input
* Documentation.
* Adding more undo checkpoints for the Widget Panel
* Quick selection of default user_data types
* Pulldown menu for system colors
* Make sure that partially typed text fields are propagated before saving
* Size and position widgets can evaluate basic math.
* Allowing x, y, w, and h as variables for formulas.
Also supporting 'i' as a counting index when selecting multiple
widgets, so setting Y: to i*25+10 arranges all selected widgets
vertically.
* Additional variables cx, etc. for children box
cx, cy, cw, ch
