* The toplevel icon is now set to the app-id, unless "overridden" by OSC-1 or OSC-0. * Implemented OSC-1 * OSC-0 extended to also set the icon * Implemented CSI 20 t - report window icon * Implemented CSI 21 t - report window title * Implemented CSI 22 ; 1 t - push window icon * Implemented CS 23 ; 1 t - pop window icon * Extended CSI 22/23 ; 0 t to also push/pop the icon * Verify app-id set by OSC-176 is valid UTF-8 * Verify icon set by OSC-0/1 is valid UTF-8
