Font weight modification support

[samouri]

Hi @dspreadbury,

First off, thank you for all the work you've done with Bravura and SMuFL. Just by reading the SMuFL spec I've learned about so many capabilities that OpenType fonts that I otherwise would never have known about.

When trying to use Bravura in websites, I noticed that while characters could be made bolder, reducing line thickness via font-weight: 100 (or other usual methods) did not work.

Do you know if there are any other ways of modifying line thickness?

Thanks!

Setting font-weight to a custom value only works with variable fonts, which Bravura is not, AFAIK.

A first smufl variable font would be incredible, though. Especially one with a printed----handwritten variable. Basically an interpolation of Bravura and Petaluma
