Don't try to be smart when chosing which parameters need their
automation updated but rather trust the list that was populated at
creation time when all relevant information had been gathered.
When requesting a size for ArdourButton, the width and height of the
button could be increased by one to ensure the center of the text would
lie exactly at the center of the button.
I initially thought that it was a good idea even when the text used for
sizing was frozen, but the main (and only?) use-case for that is to
actually freeze the size of the button regardless of the actual
displayed text, so jittering by one pixel is not welcome.
Only do the centering tweak if there is no sizing text.
This [hopefully] fixes jack1 zombification on session-load with large
plugin-states. Previously it was possible to block
Route::process_output_buffers().
Remove the LocaleGuard so that the value of LC_NUMERIC is that of the users
locale and sscanf will parse the string correctly. For instance, with a locale
like nl_NL or fr_FR where the decimal point is different than the "C" locale,
only the number up to the decimal point will be parsed by sscanf and input
values will be rounded down.
and also allow immediate work during use latency-compute runs.
At session load, Ardour calls a plugins "set default" state (GUI thread).
Some plugins may schedule work during state-restore. Ardour immediately
proceeded to restore the actual session plugin state without processing
the already scheduled work and without calling run() for a plugin
to apply state synchronously.
This fixes a crash where aspect ratio "0.5" from harvid was interpreted
as "0" in the French locale (expecting 0,5).
Note: harvid uses a portable, not localized snprintf() implementation
