RTL SUPPORT
To enable right-to-left CSS conversion, call this function in the page's
onload event.
If there is an Arabic character set in a META tag, enable the RTL stylesheet.
It returns true if the page is right-to-left.
Example:
N.B. Safari does not add disabled stylesheets to the stylesheets
collection, so we cannot disable the sheet by defaut in the HTML.
