[FIX] FontOfPointSizeFix-nk ( [er][sm][et] works, code good )

[Alexander at Lazarevic.de]

code is good, after fileIn I haven't found anything to break, and passes
this tests

(TextStyle default fontOfPointSize: 12) pointSize 12
(TextStyle default fontOfPointSize: 99) pointSize 24
(TextStyle default fontOfPointSize: -12) pointSize 9
(TextStyle default fontOfPointSize: 11.9) pointSize 10

I think we can live with this:
(TextStyle default fontOfPointSize: 1e5) pointSize 9
