Detailed Description

Projects a visible musical-time range onto a horizontal pixel span.

Forward projection is intentionally not clipped: renderers need offscreen points to preserve the slope of lines crossing a viewport edge. The inverse is a pointer lookup and clamps to the visible range before rounding to the nearest canonical tick.
