Mauro Carvalho Chehab 70b074df4e media: fix pdf build with Spinx 1.6
Sphinx 1.6 generates some LaTeX code before each table,
starting its own environment before calling tabulary,
apparently to improve table layout.

The problem is that such environment is incompatible with
adjustbox. While, in thesis, it should be possible to override
it or to redefine tabulary, I was unable to produce such patch.

Also, that would likely break on some future Sphinx version.

So, instead, let's just change the font size on bigger tables,
in order for them to fit into the page size. That is not as
good as adjustbox, and require some manual work, but it should
be less sensitive to Sphinx changes.

While here, adjust a few other tables whose text is exceeding
the cell boundaries.

******************
Packed HSV formats
******************
Description
===========
The *hue* (h) is measured in degrees, the equivalence between degrees and LSBs
depends on the hsv-encoding used, see :ref:`colorspaces`.
The *saturation* (s) and the *value* (v) are measured in percentage of the
cylinder: 0 being the smallest value and 255 the maximum.
The values are packed in 24 or 32 bit formats.
