If DXF has attributes for text then we should use them. Otherwise we should update the tooltip to indicate that ASCII text will only be used for plain text.

@Eldar, is your text multi-line? We always plot multi-line text as graphics, but we should correctly plot a single line of italic text as ASCII.
