An angle's revolutions were painted text: only the degrees could be
dragged or typed, so full turns needed the dial or typing past 360.
fx_widgets::angle_field draws `0x+45.0°` as two hot numbers: the
revolutions (widgets::hot_int_at, ten pixels a turn, fractions adding up
between frames so slow drags still step; a typed value is truncated) and
the degrees, each keeping the other. Effect Controls, the Timeline and
the Properties panel use it, so they read and edit angles alike (the
Timeline showed `-1x-40.0°` and Properties had its own split).
Automation ids: timeline.prop.<uid>.revolutions,
effectControls.prop.<uid>.revolutions, properties.prop.<uid>.revolutions.
Regression test: angle_revolutions_scrub_and_take_typing drags and types
the revolutions in all three panels.
