Description of problem:
Setting QT_XFT = true turns on anti-aliasing for kcalc's display font, as it
should.  No other
kde applications (that I've found so far) pay any attention to QT_XFT, though. 
This includes
kedt, kate,  konsole, etc.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. setenv QT_XFT true
2. type "kcalc"
3. click "Configure" -> "Display Font".  Fonts are anti-aliased. close kcalc.
4. type "kedit".
5.  click "Settings" -> "Configure Kedit" -> "Font".  Fonts are NOT
anti-aliased.
