General default options go here:
* Borders are mid-grey.
* Body text is not indented compared to the titles.
* Page margins are a rather small 0.5in, but we need
  all the space we can get for code blocks.
* Paper size is A4: an ISO standard, and just slightly smaller than US Letter.
* Use SVG graphics for admonishments: the bitmaps look awful in PDF's.
* Disable draft mode so we're not constantly trying to download the necessary graphic.
* Set default image paths to pull down direct from SVN: individual Jamfiles can override this
  and pass an absolute path to local versions of the images, but we can't get that here, so
  we'll use SVN instead so that most things "just work".
