- Around line 571-612: Update applyPolylineColorsUnderLine so colorsUnderLine
contains exactly one color for each adjacent point pair, matching PolylinePlot’s
segment indexing and excluding pre-first or trailing areas. Iterate points with
access to the next point, determine each endpoint’s generated state via
automationPointAt, and select editedColor when either endpoint is non-generated;
otherwise use generatedColor.

Align colorsUnderLine with PolylinePlot segment indexing.
PolylinePlot uses entry i for the segment between points i and i + 1. It does not render pre-first or trailing areas. Build one color per adjacent point pair and use both endpoints when selecting the color. The current loop shifts colors because it selects each color before reading the next point.

Depends on: musescore/muse_framework#224
The colors either side of an "edited" point should appear slightly darker than their "generated" counterparts.
This PR also addresses an assertion failure in
NotationAutomationwhen creating a new score (mirroring some logic used inMasterNotation::setMasterScorewhen loading an existing score).
