 IMPLEMENTATION:
-- Code is in popupwin.c
+- buffers remain after popup was deleted.
+- do not redraw whole window when popup was changed, mark affected lines for
+  redraw.
 - Why does 'nrformats' leak from the popup window buffer???
-- Make redrawing more efficient and avoid flicker.
-    First draw popups, creating a mask, use the mask in screen_line() when
-    drawing other windows and stuff.  Mask contains zindex of popups.
-    Keep mask until next update_screen(), use when drawing status lines.
-    Remove update_popup() calls after draw_tabline()/updating statusline
-    Fix redrawing problem with completion.
-    Fix redrawing problem when scrolling non-current window
+- Add 'balloonpopup': instead of showing text, let the callback open a balloon
+  and return the window ID.   The popup will then be closed when the mouse
+  moves, except when it moves inside the popup.
+- For the "moved" property also include mouse movement?
+- Make redrawing more efficient and avoid flicker:
+    - put popup menu also put in popup_mask?
+    - Use changes in popup_mask to decide what windows and range of lines to
+      redraw?
 - Disable commands, feedkeys(), CTRL-W, etc. in a popup window.
   Use NOT_IN_POPUP_WINDOW for more commands.
 - Invoke filter with character before mapping?
