void paintScale(LayerGeometryProvider *v, const HorizontalScaleProvider *provider, QPainter &paint, QRect r, bool logarithmic)
Interface for classes that provide geometry information (such as size, start frame, and a large number of other properties) about the disposition of a layer.
int getHeight(LayerGeometryProvider *v, QPainter &paint)
Interface to be implemented by objects, such as layers or objects they delegate to, in which the X axis corresponds to frequency.
