-POSITION is a position specification. This is either a mouse button event
-or a list ((XOFFSET YOFFSET) WINDOW)
-where XOFFSET and YOFFSET are positions in pixels from the top left
-corner of WINDOW. (WINDOW may be a window or a frame object.)
-This controls the position of the top left of the menu as a whole.
-If POSITION is t, it means to use the current mouse position.
-
-MENU is a specifier for a menu. For the simplest case, MENU is a keymap.
-The menu items come from key bindings that have a menu string as well as
-a definition; actually, the "definition" in such a key binding looks like
-\(STRING . REAL-DEFINITION). To give the menu a title, put a string into
-the keymap as a top-level element.
-
-If REAL-DEFINITION is nil, that puts a nonselectable string in the menu.
-Otherwise, REAL-DEFINITION should be a valid key binding definition.
-
-You can also use a list of keymaps as MENU.
- Then each keymap makes a separate pane.
-
-When MENU is a keymap or a list of keymaps, the return value is the
-list of events corresponding to the user's choice. Note that
-`x-popup-menu' does not actually execute the command bound to that
-sequence of events.
-
-Alternatively, you can specify a menu of multiple panes
- with a list of the form (TITLE PANE1 PANE2...),
-where each pane is a list of form (TITLE ITEM1 ITEM2...).
-Each ITEM is normally a cons cell (STRING . VALUE);
-but a string can appear as an item--that makes a nonselectable line
-in the menu.
-With this form of menu, the return value is VALUE from the chosen item.
-
-If POSITION is nil, don't display the menu at all, just precalculate the
-cached information about equivalent key sequences.
-
-If the user gets rid of the menu without making a valid choice, for
-instance by clicking the mouse away from a valid choice or by typing
-keyboard input, then this normally results in a quit and
-`x-popup-menu' does not return. But if POSITION is a mouse button
-event (indicating that the user invoked the menu with the mouse) then
-no quit occurs and `x-popup-menu' returns nil. */)
