/*! \brief Character Palette for direct glyphs inserting.
The "classical" one is opened as CharSelectEnhanced instance.
Both CharSelect/CharSelectEnhanced palettes are split due:
1) initial and usage performace. The CharSelectEnhanced is too
slow to load on startup/doc opening etc. The memory footprint
is much smaller too.
2) It was one dialog before split. To show/hide "enhanced" part
caused serious mess with layouts and dialog sizes and positioning.
Now it's handled in standard way.

\note This palette is used as standard Scribus palette for ScribusDoc mainly.
\note There is 2nd usage as well - in the StoryEditor. See its docstrings.
