Extend shade.pdf test

* Tweak free gouraud test to make it more obvious when interpolation
  happens only on vertices by putting most vertices at x 0 or 100

* Add a column with colors in Lab

* Add another column with indexed color spaces for types 4-7

* Give the tensor meshes a visible color twirl (only visible in
  engines with real support for tensor meshes, e.g. acrobat
  and pdf.js)

* Add rows where the colors alternate on the corners of coons
  and tensor patches, instead of varying left-to-right

* Reorder page contents stream to contain columns in left-to-right
  order

* Reorder objects to match order they appear in /Shading dict

* Renumber objects to be ordered sequentially in file order
