change Messaging font size? (CM10.0 - Android 4.1.2 on Samsung Galaxy Exhilarate SGH-i577)

[thineownself]

the Messaging font seems smaller than the other standard system fonts...
I'd like to keep the current LCD density, and the current 'Font Size' and all that, yet change (increase) the font size JUST for the Messaging app.
is this possible?
(I keep reading about "pinch to zoom" within messaging, but it appears that doesn't apply to Cyanogenmod 10.0, or 4.1.x...)

thanks
