WINGs/wpopupbutton: paint all items in expose, not just highlighted 

paintMenuEntry was only called for the highlighted item on expose.
On X11 the X server auto-filled the rest of the window with the
background pixel, so unpainted items looked grey-but-empty.  On
Wayland the buffer starts transparent — unpainted items showed
through to whatever was behind, making the popup invisible.

Iterate all items in the expose handler so the menu's full content
is visible when it first appears.
