With bundles `ports_are_inputs()` indicates inputs that Ardour
can write to (data sinks, for playback).
BundleEditor::input_or_output_changed () set this correctly.
The rec-arm circle diameter is given by 0.5 * min (width, height).
For mono tracks the diameter is limited with the height of the
track. When more channel meters are visible the height increases and
the rec-arm circle grows.
The solution here is to constrain the rec-arm button width to its
minimum and not grow to have the same width as other buttons.
This also changes the default meter-height so mono and stereo tracks
have the same height (with default scaling).
The calculation to round the distance to seconds has to be performed
using floating point maths, not just the result being cast to double.
The time-granularity must not be zero.
* Shorten long labels
Those increase the x-offset for the data table column on the right.
* Shorten some long ComboBox texts
* Reduce min. slider controller width
* Tag some long labels and dropdowns that are currently the bottleneck
* Split "Signal Flow" pages to reduce height requirement
-> Signal Flow & -> Solo/Monitoring
The latter is just control logic, no signal flow changes.
* Group CPU/FPU performance Options
* Move Region-Analysis to Metering (it is not performance related)
* moved some wrongly-parented items into a more sensible location
(import & export options for example)
* broke some busy pages into separate sub-tabs: Size+Scale,
MIDI Port configuration, Timecode Generators
* added "Performance" tab to consolidate some of the tweakier prefs
* moved the order of tabs around so the "indented" ones were not
so intermixed with the non-indented ones
code changes:
bbt_ variables don't need to be global to editor; we only use these in compute_bbt_ruler_scale now anyway
drive the ruler with the same coarse-ified bbt_ruler_scale that we calculate for the snap grid
The location name is only pushed to the backend during
ExportTimespanSelector::add_range_to_selection() which in turn
is only called when timespans are updated.
