[Lazarus] WordWrap in TLabel

[Jürgen Hestermann]

Does anybody know where the routine resides that actually
does the splitting into lines of TLabel.Caption (if WordWrap is true)?
I don't like it's behaviour and want to change (overwrite) it.

Currently, long lines are not wrapped when no spaces exist.
I am wondering why this is the case because the reason for wrap is,
that the whole text should be visible all the time. And that's not the case now.
