[Bf-funboard] Relative sync scale of timelines

[David McSween]

I propose a way to sync-scale windows to predetermined values.

I was wondering if it would be possible to stack different timelines and
perform a locked zoom, in the same way as Quad view in 3D window (with Box
on).
With a Parent timeline and locked children timelines, that resize to parent
view. The children views would scroll and scale horizontally with Parent.

For example I would like to animate curves or dopesheet values relative to
other information like VSE waveform and they all scale to a master view.
In this case I would zoom to fill the view with an audio strip, then
conform zoom the f-curve view on top. This way I can animate the audio
levels or any other selected objects variables, all relative to a preferred
display (in this case the VSE).

I know that markers fit this function but they can be misleading if zoomed
out and there can be very many of them, causing confusion.

A locked auto-scroll like the 3D view's Quad Box function would be nice for
timelines. It would just be a relative value to playhead which is already
synchronised.
