The local variable ‘freq’ should be renamed

	gdouble scale = widget->priv ? *(gdouble *)widget->priv : 1.0;

The local variable ‘freq’ should be renamed, as it may not be necessary to represent frequency. It may cause a bit of confusion for source code reading, and similar conditions should be checked.
