[alreq] Section on slanted font styles (Italic, Oblique, Iranic, ...)

behnam has just created a new issue for https://github.com/w3c/alreq:

== Section on slanted font styles (Italic, Oblique, Iranic, ...) ==
As discussed on the weekly meeting, we want to document the existing 
methods for using slanted text, slanted to the left or to the right, 
as it's been a common practice for the past few decades.

The goal is to document the details of the existing methods, and try 
to find the common names for them.

Also, we want to note that using slanted text is **not** a traditional
 way of emphasis/quotation/etc, but a half-baked borrowing from 
Latin-script Italic/Oblique methods.
