Rotation of Glyphs

[rvilarl]

VexFlow uses OTF fonts including SMUFL glyphs. I have suggested to use OpenType.js for rendering, but some glyphs require a 90° rotation.
See w3c/smufl#218 (comment)
See https://www.smufl.org/version/latest/range/multiSegmentLines/

Expected Behavior

A method should be provided to rotate the glyphs.
(I am not an expert, perhaps there is already a way to do this, that I do not know)

Possible Solution

Glyph functions might include an additional optional parameter to indicate the rotation angle.

Context

I need to render the multi segment lines from SMUFL fonts vertically.
See https://www.smufl.org/version/latest/range/multiSegmentLines/

Ok it seems that it is not supported. I saw the comment in the code

// TODO rotation and stretch currently not supported

Any plan to support it?

No plan here, but a PR is always welcome :)
