Review request for kdelibs.


Summary
-------

Changes KFontDialog and related classes (KFontChooser, KFontRequester) to support fractional font sizes (currently, only one decimal digit is supported, I guess this is sufficient to close the bug report).

QFont already had support for fractional font sizes. Applications that do not use QFont::pointSizeF() but pointSize() will get the rounded size. Most applications, however, simply request a font, use it, or store it using KConfig, so they will support fractional font sizes transparently.

There may be a need for a KFontSizeFAction class in KDE, but before I add anything to KDE, I better ask for a review :)
