profile: set alignment and scale of DiveTextItem at construction

Browse source 
Alignment and scale of DiveTextItems are never changed. Therefore,
pass them at construction time. This makes things much easier
if we want to cache the rendered text [currently the text is
rerendered at every paint() event].

This also removes the "parent=0" default parameter of the
constructor, because inadvertently leaving out the last argument
led to a subtle bug.
