void gui_winmod(xml) string xml
<WINDOW TOP='pos' LEFT='pos' WIDTH='size' HEIGHT='size' UNITS='units' LKEYS='enum'/>
where 'pos' is either 'center' where the window is centered on the screen, or 'n', 'size' is either 'auto' where the window adjusts to fit its contents, or 'n', and 'units' is either 'cell' or 'pixel' (default). If 'n' is prefixed with '-' or '+', then 'n' is a delta applied to the window's current setting for that value; otherwise it is an absolute value.
LKEYS sets the keys that will be treated as local keys for any lists in that window that have the Local Keys attribute set. The key names must match the WPF Key enum. These definitions are found here: http://msdn.microsoft.com/en-us/library/system.windows.input.key.aspx The key names may be prefixed with Alt+, Ctrl+, or Shift+ if desired.
