[Gtk-sharp-list] drawing problem during resize of panedwidget, handle/toolbar always-on-top, window resize performance

[Gennadiy Donchyts]

Todd, thanks a lot for a tip with SizeAllocate and QueueDraw, it is more
correct in this way :) ... but it is not intuitively understandable even
after reading the documentation that it is necessary to do it like this.

That is absolutely the wrong way to do it.

What you want to do is hook up to the widget that gets misdrawn
SizeAllocate and QueueDraw there.

Hopefully this win32 bug will get fixed soon though.
