core/window: Do not apply limits if no previous size has been stored

Browse Source 
A previously stored width and height of 0 signifies that no previous window
size has been stored. This might be the case if an application starts in
maximized or fullscreen mode. If no previous window size has been stored,
the client needs to determine its own size.
