As became apparent in #1558, not all IRenderContext implementations support the maxSize parameter of DrawText(...).

I think we could address this by:

• Remove the maxSize parameter from IRenderContext.DrawText()
• Add a RenderingExtensions.DrawText() extension method with the maxSize parameter
• Implement this functionality using a combination of text measurement and regular clipping

That way I think it should be possible to get this to work on all platforms that natively support clipping.

I might have a look at this later.
