   #     standard HTML ones:
   #      TeXwrap   - Governs how the tex target will try to wrap text around
   #                  horizontally aligned images.
   #      TeXwidth  - The width of the image when rendered for print (mm).
   #      TeXheight - The height of the image when rendered for print (mm)
   #         (Note there seems to also be support for this as a % of page size)
