Detailed Description

QML-visible canvas item that renders the tempo automation curve in the background of the tempo lane.

Draws the continuous tempo curve (constant steps and linear ramps) behind the tempo objects using the GPU-accelerated QCanvasPainter API. The data is read from the TempoObjectManager (the same objects rendered as pills), so the curve always matches what is shown and edited. The vertical range is the project-wide min/max of all tempo objects.
