Hi,

Thank you John, I have just committed your patch.

There are basic Save()/Restore() functions, but IIRC they do not store
the font settings, but are mostly used to maintain the transformation
matrix.

I am not sure about the best solution here. None of the drawing
functions make any assumptions about the used drawing settings (color,
line width, stroke/fill, etc.), so perhaps this should be the same for
texts. Alternatively there could be a Reset() function, but anyway you
are likely to set the text line width and size, so effectively you would
just restore the attributes. I am open to discuss other ideas.

Cheers,
Orson
