Gabriel Matozo c4e3dc272c Render: a dimmed header's borders keep one tone where they meet (#2946) (#3725) ...

#2947 fixed the fade by drawing a dimmed layer inside a single opacity layer,
but left no regression test for the tone: where a header table's borders cross,
a crossed or shared rule would quietly come out darker than a rule that is not
drawn on top of anything, and the undimmed view and the PDF export would not
agree with the screen.

The test renders the same page with the header dimmed and undimmed and checks
three rules: the darkest pixel at a crossing of a cell's top and left rules,
the darkest pixel on a border two neighbouring cells share, and one on an
outer border well clear of both. With the fade done as one layer, the
crossing and the shared border keep the tone of an isolated rule; measured
against a clean full-strength render, the dimmed tone is 0.45 of the
background, not 0.45 squared.
