>   `ly:stem-tremolo::height`

>   Hard coded extent in Y direction.

> `X-extent` (pair of numbers):

>   `ly:stem-tremolo::width`

>   Hard coded extent in X direction.

> `stencil` (unknown):

>   `ly:stem-tremolo::print`

>   The symbol to print.

> `slope` (number):

>   `ly:stem-tremolo::calc-slope`

>   The slope of this object.

> `beam-width` (dimension, in staff space):

>   `ly:stem-tremolo::calc-width`

>   Width of the tremolo sign.

> `style` (symbol):

>   `ly:stem-tremolo::calc-style`

>   This setting determines in what style a grob is typeset. Valid choices depend on the `stencil` callback reading this property.

> `beam-thickness` (dimension, in staff space):

>   `0.48`
