Sizers are extremely powerful, but it is common knowledge that they
can be equally confusing. IMHO there are two reasons for this
confusion. The first reason is that the arguments are far from
intuitive and perhaps Chris's API would help with this. (I have
taken a similar approach and implemented three keyword arguments:
resize, margin, and align.)

But the second source of confusion is that if one uses nested
windows (panels) and nested sizers to any degree, one ends up with
two entirely different containment hierarchies. The way I have
handled this is to build sizers into my panels, so that adding a
component to the panel automatically adds it to the sizer. No muss,
no fuss.
