Oh my. I suppose it's not be used directly in TCustomControl, but on
descendants.
What about descendants that dont use it? Dont need it?
OnPaint can be even undesired in some controls
If some descendants needs OnPaint is pretty simple to add with the benefit
of choosing where to call.
This is not in question. It's already there.
Yes but is useless. Even delphi does not has.
For an descendant overriding Paint is easier then assigning an OnPaint
handler. And the descendant may not want to expose OnPaint to users case
when will just be using extra memory
