Small feature request - shadow underneath text (can be used for glow I suppose as well if you're into that kind of thing)

Use case: Yellow background with white text, the default colours are difficult for some people to parse in low contrast environments quickly. Whilst changing the colours would also be better, legibility can be improved significantly by simply adding a shadow underneath the text

So, access to .setShadowLayer(...) (a la TextView) would be nice :)
