Step by Step for increasing font size

[xenthal]

i assumed it was:

<Font name="FLYING_NUMBERS" face="Sony Sketch EF" size="51" weight="Normal" italic="No" antialias="Full"/>
<Font name="FLYING_NUMBERS_ITALICS" face="Sony Sketch EF" size="51" weight="Normal" italic="Yes" antialias="Full"/>
<Font name="FLYING_NUMBERS_SHIELDED" face="Sony Sketch EF" size="55" weight="Normal" italic="No" antialias="Full"/>
<Font name="FLYING_NUMBERS_SHIELDED_ITALICS" face="Sony Sketch EF" size="55" weight="Normal" italic="Yes" antialias="Full"/>

part of the file like in AoC (as you see i edited it trying to change it)
but the editions i made had no effect whatsoever.
