2999 NB: there used to be some code here which set the initial size of the

3001 specified. This was wrong because wxWidgets programs often assume
3002 that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
3003 it. To see why, you should understand that Windows sends WM_SIZE from
3004 inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
3005 from some base class ctor and so this WM_SIZE is not processed in the
3006 real class' OnSize() (because it's not fully constructed yet and the
3007 event goes to some base class OnSize() instead). So the WM_SIZE we
3008 rely on is the one sent when the parent frame resizes its children
3009 but here is the problem: if the child already has just the right
3010 size, nothing will happen as both wxWidgets and Windows check for
3011 this and ignore any attempts to change the window size to the size it
3012 already has - so no WM_SIZE would be sent.

3021 //
3022 // 2. it is buggy for frames with wxFRAME_TOOL_WINDOW style for which
3023 // the default is for whatever reason 8*8 which breaks client <->

3025 // does and the simplest way to fix it seemed to change the broken

3028 // 3. there is just no advantage in doing it: with x and y it is
3029 // possible that [future versions of] Windows position the new top
