Please describe the problem:
When you select "Apply Font" from LargePrint theme, a new large font is applied, 
however when you select another non LargePrint theme the font does not revert
back, you really should be given the option to "Apply Font" again to revert back.

Steps to reproduce:
1. Launch gnome-theme-manager ensure current theme is not a LargePrint theme
2. Select LargePrint theme, and click "Apply Font" for selected font. You
desktop now gets a nice large font size.
3. Select any other non-large size font theme, the font does not revert back to
a normal size and you are not even given an option to "Apply Font" again.


Actual results:
Large Font is left on desktop, even though you are not using the LArgePrint theme.

Expected results:
Font to be reverted back to normal or at least an option to Apply Font again.

Does this happen every time?
Yes

Other information:
Only way to work around this issue is with Font Preferences Capplet.
