I've seen your follow-up message about using FXApp#normalFont as a
valid substitute, but just wanted to clarify something.

A device context (i.e. an FXDC instance) doesn't have a default text
font. So if you don't explicitly set it yourself (using the
FXDC#textFont accessor in FXRuby 1.0, or FXDC#font in FXRuby 1.2) then
yes, it will be nil.
