one bug for the Qt/dialog people

[Uwe Stöhr]

Since 1.4 LyX doesn't understand decimal points in the bounding box sizes of graphics: Inserting a decimal point isn't possible and existing 
graphics that already have decimal points (inserted with LyX 1.3) can't be modified.

The bug is also in LyX1.5svn. Perhaps fixing this is easy for the dialog 
people; it would squash two bugs:

and
