ViewClockStrip

The playback strip of the viewport (fea-result-experience §FRX-4): play and pause, a scrub slider for the phase while paused, the speed of the view clock, and the cycle and the scale of the animated deformations.

In the namespace construct::ui. Declared in src/libs/libconstruct/construct/ui/ViewClockStrip.hpp.

Detailed description

It shows while an item animates or a phase is fixed, as a row of the corner HUD. Play, pause, the scrub and the speed change the view only: the clock, never the document. `construct.view.clock` reads and sets the same driver. The cycle and the scale are presentation, so the strip only asks for them (cycleChosen(), scaleChosen()), and the shell writes the deform presenters in one undo step.
