Notice that versions 0, 1, 2 & 3 of the table are supported. Notice also that the Panose variable has been broken down into its elements.
METHODS
$t->read
Reads in the various values from disk (see details of OS/2 table)
$t->out($fh)
Writes the table to a file either from memory or by copying.
$t->XML_element($context, $depth, $key, $value)
Tidies up the hex values to output them in hex
$t->XML_end($context, $tag, %attrs)
Now handle them on the way back in
$t->update
Updates the OS/2 table by getting information from other sources:
Updates the "firstChar" and "lastChar" values based on the MS table in the cmap.
Updates the sTypoAscender, sTypoDescender & sTypoLineGap to be the same values as Ascender, Descender and Linegap from the hhea table
(assuming it is dirty) and also sets usWinAscent to be the sum of Ascender+Linegap and usWinDescent to be the negative of Descender.
