view layer/TimeRulerLayer.h @ 1447:8afea53332f3 single-point

Add option to make pane sizes auto-resize-only (i.e. remove user control via a splitter); also place alignment views above panes instead of below, meaning the extra bit of space that we currently have for the pane without one at least goes to the primary pane
