/**
* A menu button posts a popup menu when clicked.
* There are many ways to control the placement where the popup will appear;
* first, the popup may be placed on either of the four sides relative to the
* menu button; this is controlled by the flags MENUBUTTON_DOWN, etc.
* Next, there are several attachment modes; the popup's left/bottom edge may
* attach to the menu button's left/top edge, or the popup's right/top edge may
* attach to the menu button's right/bottom edge, or both.
* Also, the popup may apear centered relative to the menu button.
* Finally, a small offset may be specified to displace the location of the
* popup by a few pixels so as to account for borders and so on.
* Normally, the menu button shows an arrow pointing to the direction where
* the popup is set to appear; this can be turned off by passing the option
* MENUBUTTON_NOARROWS.
