/**
* There are multiple ways to store the two different areas of a vcl : : Window .
* But this representation is hopefully less error prone from the used types
* and more clear in what values in - or exclude the non - drawable window frame .
*
* There are especially two things to remember :
* * pos ( ) is the top - left position of the window frame
* * size ( ) returns just the drawable client area
*
* So these values actually don ' t represent any " real " geometry of either the
* outer frame or the inner client area of the window . That ' s my reason for
* naming the rectangle function posSize ( ) instead of geometry ( ) . Also to not
* be confused with Qt ' s geometry ( ) function . YMMV .
*
* LO already is supposed to use this schema . FWIW , the Qt documentation claims
* " The differentiation is done in a way that covers the most common usage
* transparently . " AFAIK this is common for most / all platforms / UI toolkits .
*
* The API is kept largely overload free , as we can now use list - initialization .
