How do you set @Book { @Title{} } font size?

The @BookSetup setup file symbol has a @TitlePageFont option.  If
you don't like what you are getting on the admittedly very hard
wired front page, you can always switch to using the @OnTitlePage
option of @Book, which places an arbitrary object on the title page
instead of the usual arrangement of title, author, and so on.

The default value is 2.5f, which for an initial font of 12p is
30p.  Perhaps you didn't notice the 3p difference?  I tried

   @SysInclude { book }
   @Book
       @Title { 5p @Font { A Title } }
   //
   @Chapter
      @Title { First Chapter }
   @Begin
   @LP
   Stuff.
   @End @Chapter

just now and certainly got an unusually small title.  But I
don't think this is the right way to do it, mixing up format
with content always costs in the end.
