Details - I would like to implement some animation-heavy widgets but there is a 
problem. My animation is implemented with the help of "update" signal emitted 
on timer. Everyting works fine while there are one or two such widgets but when 
more added, CPU usage grows drastically. The reason is that the "updated" 
signal causes ALL widgets to redraw themselves and hance do a lot of useless 
work in most cases. My original intent was to implement separate "redrawn" 
signal to redraw only the widget which emitted it(and reimplement current 
layouts like sizers in wxWidget) but I don't see how to do that without 
breaking current API. Could you recommend something? Thanks in advance!
