Hey Dmytro,
It could very well be - nothing comes to mind that works this way other than
stems. The more I think about it, the more I realize that Y-extent is more
meant to be the vertical portion of a bounding box and, thus, can greatly
overshoot or undershoot the actual grob.
The most computation-friendly way to decouple Y-extent from the stencil without
having to do calculations twice is to do what is done in spanners like
TupletBracket and Beam - namely, use a positions property to hold an interval
of y positions. stem::height and its pure equivalent would simply pass back
these values, and stem::print would use them to print the stencil. Then, an
override to Y-extent would not besmirch the stencil.
Alternatively, to avoid the addition of a property, the stem stencil function
could make a call to Stem::internal_height instead of making a call to extent,
although this would duplicate a long series of calculations.
Both of these are 15 minutes of work and, hopefully, if it becomes pressing
during my absence, someone can implement them. If anyone foresees needing to
implement this during my absence and does not understand what I'm talking about
above and/or would like more explanation, don't hesitate to get in touch!
Cheers,
MS
