ArdourButton draws a custom insensitive background, using
the color "gtk_background". This can conflict with gtk's
insensitive background color when using round-corners.
A Pango::Layout created by Gtk::Widget::get_pango_context ()
does not have any font set. The Font is inherited from the
layout's context.
The actual font is set when the layout is used in
on_expose_event() via get_window ()->create_cairo_context ().
In some cases we rely on the font-size to calculate the widget's
size before rendering. At this point in time there is no drawing
context from which to inherit the style.
Furthermore, even after a call to `ensure_style()` in the c'tor
of a Widget get_font() simply returns the default value.
All Widgets that rely an Pango::Layout font size during
size-requests have to explicitly set the font.
This fixes various overlarge buttons with the initial default layout.
This follows 5a41ca8fdf and df1e6fda2d.
Even though this kind of precision is rarely needed, rounding
to a single digit is inconsistent with various places that display
more than one digit, or allow more accurate control.
When a button has a fixed size, there's no need to call queue_resize().
This fixes an issue with the ArdourClock info displays when slaved.
The Timecode and Delta display text changes in small intervals and
caused excessive CPU load due to GUI size-requests + redraws.
Actions for hide/show/attach/detach tabbables use hard-coded names which are not
translated. Using Tabbable/WindowProxy::name() to lookup the action will fail,
since the name can be translated. This changes just removes the option to not
provide a menu-name when creating these objects, and uses the name menu-name
when looking up an action by name
This fixes Virtual-keyboard velocity selection when scrolling
to numbers that are not explicitly in the menu-list.
(hopefully this does not introduce some recursive signals
for other ArdourDropdowns, fingers crossed).
Previously this was inherited via PBD.
On MacOS/X, this adds
"-undefined dynamic_lookup -flat_namespace"
and various "-framework .." options to linkflags
Without this flag, .dylibs fail to link usually because
of missing `-lintl` (Undefined symbols: "_libintl_dgettext")
On other systems this is a NO-OP:
CFLAGS_OSX, CXXFLAGS_OSX and LINKFLAGS_OSX
are only set on the darwin platform.
This fixes an issue with scroll-wheel control which uses `get_active()`.
It work around an issue with gtkmm:
const MenuItem* get_active () const
void set_active (guint index)
and MenuList::activate_item() not emitting activate_item().
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
