Portrait vs. landscape orientation for Tabloid paper

Portrait vs. landscape orientation for Tabloid paper

[Pavneet Arora]

I believe that the definitions for portrait and landscape orientation
for Tabloid/Ledger paper are flipped.

In the following MWE using Hans' clue to using \scaling directive, I am
having to specify landscape in order for the page to be set in portrait.
This observation is confirmed when I retrieve the document properties
using evince under Bodhi Linux and under Ubuntu 12.04 (<ALT><ENTER>
brings up the document properties).  With this MWE, the properties under
both systems is shown as "Tabloid, Portrait (11.00 x 17.00 inches)"

Have I got this right?

MWE:

	width=10in,
	topspace=1.0in,
