Using ContentStream#write makes GhostScript complain about origami

[JasonBarnabe]

Solution seems to be to first

page.add_font(Origami::Font::Type1::Standard::Helvetica.new.pre_build, :Helvetica)

and then

      contents.write('my text', {
          x: 30,
          y: 30,
          size: 8,
          leading: 8 * 1.2,
          font: :Helvetica,
      })

I'm still unsure what should be the correct behavior if no font is passed as an argument.

I could simply reuse the current font used in the graphics stack of the page.

Any of these seem sensible to me:

• Make font a required argument
• Use a (working!) default font
• Use a font used elsewhere in the PDF (is there always at least one font?)

No matter what you choose, please document it and update the examples.
