handle UNKNOWN keyboard resizing state
2002-06-19 Havoc Pennington <hp@pobox.com> * src/display.c (meta_resize_gravity_from_grab_op): handle UNKNOWN keyboard resizing state * src/keybindings.c (process_keyboard_resize_grab): implement keyboard resize key handling somewhat (only vertical resize works, left/right arrow not implemented, and visual feedback of the edge we're resizing isn't implemented) * src/window.c (menu_callback): start keyboard resize grab when it's chosen from the menu
