+This test passes if the pages generated are identical for both vertical-lr and
+horizontal-tb writing-modes by means of making the size of the content we are
+printing equal to exactly the same number of pages being generated in each
+writing mode.
+This sizing is calculated like so:
+
+1. It is important to note that irrespective of the writing-mode, the print
+ UI always lays out printed pages vertically. Therefore, it is possible
+ to equate the printed content of two different writing modes if both
+ cases generate the exact same number of pages (and of course no text on
+ the pages, which is why we use background color since it is independent
+ of writing mode).
+2. To avoid an unnecessary vertical scrollbar (since scrolled content will be
+ clipped anyway in the reftest snapshot), the maximum number of 5X3in pages
+ that we should generate for the reftest snapshot are equal to 3.
+3. Considering a margin of 0.5in on each side of the 5X3in page, we get the
+ size of the page content area to be 4X2in per page and to generate exactly 3
+ printed pages from this in horizontal-tb writing mode, we need a printable
+ area of 4X6in (as used below).
+
+Similarly, the size for the test case printable area is calculated, only
+considering a vertical-rl writing mode.
+
+It is important to note here that when printing this test outside of the test
+harness, the background color will not show since we omit printing and
+previewing of background colors by default via the browser printing path.
