Well, if custom initializer want to tweak the general settings, it 
should tweak it not just during initialization but during regular 
changes too? For example if sub class want to tweak its bounds it should 
do it in setBounds not in initialization.  I'll create separate RFE for 
refactoring of peer initialization.
