How to get ALL available font styles using ImageSharp?

[SulfuricAcidH2SO4]

I would like to be able to access all the styles of a font.
Let's say for example I want to use the font "Bahnschrift" which comes preinstalled with Windows, with the specific style "SemiCondensed". Right now, after getting the family, I am not able to see all the available styles as doing :

family.GetAvailableStyles()

will just return a collection of enumerators with the fonts in the defined styles. As a consequence I am not able to load that specific style.

I checked The documentation, but have not been successful in finding any way to specify a custom named font style.

I am welcome to any suggestion, thanks!

Bahnschrift is a variable font which is currently unsupported by the library.

See Issue #5

We have a WIP PR to allow supporting CFF2 variable fonts but at this time now work has been started to allow support for TTF fonts.
