Detailed Description

A button component that shows the current transpose quantization state and opens a callout to edit it.

The TransposeQuantizeButton displays a set of notes (like keys) and which ones are active in the quantization. When clicked, it launches a TransposeQuantizeCallOut for editing. It can notify its listeners about quantization changes.
