There are two big tables here that are very hard to adjust its
size.

The first one would fit into one page, but the latex.py logic
at Sphinx auto-switches to longtable when there are more than 30
rows. There's no way to override without coding.

The second one is really big, and won't fit on a single page.
So, it has to use tiny font to fit.

It is painful to put code/verbatim code in bold. It seems that
the only way is to arrange it like:
	``foo``
	    bar

At least on LaTeX output, when this happens, the "foo" string
is not hidentable/breakable. The entire string should fit into
a single line.

Add a workaround for this ReST limitation by splitting the
foo string into two strings, on separate lines. The output
is not the best, but it works.

Sphinx is really pedantic with respect to the order where
table tags and references are created. Putting things at
the wrong order causes troubles.

The order that seems to work is:

	.. raw:: latex

	.. tabularcolumns::

	.. _foo_name:

	.. cssclass: longtable

	.. flat-table::

Reorder the tags to the above order, to avoid troubles, and
fix remaining warnings introduced by media recent patches.

This table has several troubles:
	- a duplicated "struct" on its name;
	- a reference to a V4L version 1 struct that will never

	- misses hints for LaTeX output (column size and longtable

Fix mosto fo the tables there in order to make them fit at the

There are, however, two exceptions: RGB and YUV big tables,
where adding the raw latex adjustbox caused the tables to not
be properly formatted. I suspect that the problem is because
those are long tables, but not really sure.

The thing is that Sphinx lacks an "adjustbox" tag that would
avoid the raw latex hacks.

There's a bug with LaTeX output on flat-tables with Sphinx 1.4.5
that prevents references at a cell span to be broken. As the
text is indeed too long, it makes sense to place the reference
to the pictures showing the VBI limits as a footnote.

That makes the text easier to read and also solves the issue

Adjust the tables to fit at the LaTeX and PDF outputs.

I wrote a previous patch RFC to show the big table in landscape,
but it makes harder to read on displays.

So, instead, let's use the adjustbox to shrink the size of those
long tables, as the table size can still be visible on screen,
and it is a way better to read in horizontal position and
visible if printed.

LaTeX doesn't handle too well auto-width on tables, and ReST
markup requires an special tag to give it the needed hints.

As we're using A4 paper, we have 17cm of useful spaces. As
most media tables have widths, let's use it to generate the
needed via the following perl script:

my ($line_size, $table_header, $has_cols) = (17.5, 0, 0);
my $out;
my $header = "";
my @widths = ();
sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) }
while (<>) {
	if (!$table_header) {
		$has_cols = 1 if (m/..\s+tabularcolumns::/);
		if (m/..\s+flat-table::/) {
			$table_header = 1;
			$header = $_;
			next;
		}
		$out .= $_;
		next;
	}
	$header .= $_;
	@widths = split(/ /, $1) if (m/:widths:\s+(.*)/);
	if (m/^\n$/) {
		if (!$has_cols && @widths) {
			my ($tot, $t, $i) = (0, 0, 0);
			foreach my $v(@widths) { $tot += $v; };
			$out .= ".. tabularcolumns:: |";
			for ($i = 0; $i < scalar @widths - 1; $i++) {
				my $v = $widths[$i];
				my $w = round(10 * ($v * $line_size) / $tot) / 10;
				$out .= sprintf "p{%.1fcm}|", $w;
				$t += $w;
			}
			my $w = $line_size - $t;
			$out .= sprintf "p{%.1fcm}|\n\n", $w;
		}
		$out .= $header;
		$table_header = 0;
		$has_cols = 0;

Both tables on this rst file were not shown right, as they miss
the proper tag (tabularcolumns) to specify the column widths
required for PDF and LaTeX output.

Also, the second table is too big to fit into one page. So,

two pages.
