Use double precision floating point for the screen size to reduce the rounding issues when using fractional scaling. Introduce a couple of simple convenient functions that round the floating point value into an integer and use it in place of directly accessing the xwl_screen width/height for integer computation. This is preparation work for the introduction of fractional scaling, there should be no functional change at this point.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
