handle = pcontext:GetFontOptions()
This function does not report options that are derived from the target surface by pcontext:UpdateContext().
This function returns the Cairo font options object previously
set on the context, or NULL
if no options have been set. The
return object is owned by the context and must not be modified or
freed. You can use cfontoptions:IsNull() to check if
the returned object is NULL
.
