+ NB: there used to be some code here which set the initial size of the
+ window to the client size of the parent if no explicit size was
+ specified. This was wrong because wxWidgets programs often assume
+ that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
+ it. To see why, you should understand that Windows sends WM_SIZE from
+ inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
+ from some base class ctor and so this WM_SIZE is not processed in the
+ real class' OnSize() (because it's not fully constructed yet and the
+ event goes to some base class OnSize() instead). So the WM_SIZE we
+ rely on is the one sent when the parent frame resizes its children
+ but here is the problem: if the child already has just the right
+ size, nothing will happen as both wxWidgets and Windows check for
+ this and ignore any attempts to change the window size to the size it
+ already has - so no WM_SIZE would be sent.

+ // empty frame of most of wxWidgets samples for example)
+ //
+ // 2. it is buggy for frames with wxFRAME_TOOL_WINDOW style for which
+ // the default is for whatever reason 8*8 which breaks client <->
+ // window size calculations (it would be nice if it didn't, but it
+ // does and the simplest way to fix it seemed to change the broken
+ // default size anyhow)

+ // 3. there is just no advantage in doing it: with x and y it is

+ // level window in some smart way which we can't do, but we can
