<STRONG>new_panel(win)</STRONG>
- allocates a <STRONG>PANEL</STRONG> structure, associates it with
- <STRONG>win</STRONG>, places the panel on the top of the stack
- (causes it to be displayed above any other
- panel) and returns a pointer to the new panel.
-

- refreshes the virtual screen to reflect the rela-
- tions between the panels in the stack, but does not
- call doupdate() to refresh the physical screen.
- Use this function and not <STRONG>wrefresh</STRONG> or <STRONG>wnoutrefresh</STRONG>.
- <STRONG>update_panels</STRONG> may be called more than once before a
- call to doupdate(), but doupdate() is the function
- responsible for updating the physical screen.

- moves the given panel window so that its upper-left
