If we don't do this, we can have binary compatibility issues later.
For example https://codereview.qt-project.org/#change,41700 will change
the behavior of setWidth and setHeight to call setSize instead of
setGeometry, because we don't want changing the height to also set
the position of a window; if x and y are left uninitialized it needs
to remember that fact. But if setWidth is left as an inline method,
calling setGeometry, then an application which was built with 5.0
would behave differently than an application built with 5.1, even if
Qt is upgraded after the application was built. To generalize,
setters should never be inlined.
