A recent support ticket came up about changing font sizes. After a bit of research, it appears we already have functionality to do this. The option doesn't appear to be in the GUI though. in this function... QFont KoDockRegistry::dockFont()

I was thinking about adding a GUI option in the general preferences that would read/write out the setting for this. This is what it would look like...
[checkbox] Use custom font size for dockers (needs restart).
if checked....
show a another input field that defaults to [10] points. Artist can change the number and hit save.
Is there a known reason why setting this variable was removed? maybe it get lost somewhere.
