Work around broken wxWindow::SetId() in wxMSW 3.0 in XRC code.

As wxWindow::SetId() doesn't update the ID at the Windows level in 3.0 and
can't be modified to do it because of ABI compatibility concerns, work around
this in the code calling SetId() in XRC wxUnknownControlContainer itself.

Closes #3697.

Fix wxMSW wxCheckListBox appearance when using larger than normal fonts.

Update the height of the items when changing the font to ensure that there is
enough space to show the item text when using fonts larger than normal.

Fix getting position of wxPopupWindow in wxMSW.

Don't offset the returned values by the parent window origin unnecessarily: as
popup windows are created as children of the desktop window in wxMSW, their
coordinates are already expressed in screen coordinate system (which is
exactly the same as display window coordinate system) and we must not try to
translate them to it once again, this is completely wrong and was probably a
left over from earlier wxPopupWindow implementation in which it wasn't created
as a child of desktop.

In 3.0 branch we still need to continue overriding virtual DoGetPosition() for
ABI reasons, but don't do anything in it any more.

Closes #4440.

Fix wxMSW build without PCH after recent wxListBox font fix.

This should have been part of r76671.

Don't assert in wxOSX if a shaped window doesn't define a valid shape.

A window with wxFRAME_SHAPED style can still not defined any valid shape
actually, in which case wxFRAME_SHAPED should be just ignored.

Show the shaped frame with start shape initially in the sample.

It's not clear that setting the window shape actually works if the initial
shape is not set.
