width and height are variables whose current values specify the
pixel width and height of the window. When non-zero values are supplied, these
are used to specify the initial width and height of the window. If the window
is re-sized (see %ww - Window Style) then the variables width and height are
automatically updated accordingly.
Alternatively, if zero values are supplied, the window is given a default size
that suits its contents. width and height will be updated to
these values and will also be changed when the window is re-sized. If code is
added to save these settings, then the values can be used when the same window
is next opened.
Special values are used to represent a maximised window. Consequently, if the
dimensions of a maximised window are saved and used to re-open the window, the
window will be restored in its maximised state.
