Visualizer widget

Visualizer draws audio spectrum bars that react to whatever is playing on your PC, painted on a fully transparent canvas with no panel or background. Choose the linear layout, where bars rise from a faint baseline across the width, or radial, where they radiate outward from a ring. When nothing is playing you see only the thin baseline, and the loop parks itself so an idle visualizer costs no CPU. Set the number of bars (8 to 3840, up to one per pixel); the count snaps to the nearest one that gives every bar the same pixel width. Or turn on Fixed bar width, set the width and gap in pixels, and the bar count follows the size of the widget. Let them follow your theme accent color or pick a custom one.
