gcc can recognize various regexps in comments. Since C++17 provides
[[fallthrough]], using /* fallthrough */ consistently seems
appropriate until we switch to C++17.

* unify line-width calculation
* thin line-width, approximate thickness of
glyph stroke width at same UI scale
* don't use outlines (except main tool buttons)
This fixes issues of generic buttons with bright-theme
* pixel align some lines
A "fall through" comment is most portable way to indicate
"no break, fallthru" cases.
* __attribute__ ((fallthrough)) // is not portable
* [[fallthrough]]; // is C++17
Add option to use ArduorButton as standalone Toggle/Checkbox.
Usually ArdourButton relegates this to Actions or is backed by Config.
This allows to use the Button as standalone Toggle, get_active()
It should maybe be a derived Class, but ArdourButton is already beyond
that..
After over 17 years of honorable service to the Ardour Codebase.
ClickBox and AutoSpin are retiring into the git nirvana.
We're glad for the duty, decency, reliability, dignity, respect which
these classes brought to Arodur and look back in gratitude on their years
of service.
PS. First one to say "cruft" will be fired.
Currently, the scroll handler obeys to the page increment, but instead
of using the step increment for more precise scroll, it uses an
hardcoded one tenth of the page increment.
Use the step increment instead since it has been filled with sensible
values by ArdourFader's users.
The queued resize will only happen trigger a size-request when the
widget is realized, and on_size_request() calls ensure_layout().
Moreover, this over protection meant that sometimes a resize wasn't
noticed by the button containers.
