/* Clear garbaged frames.
/* Clear garbaged frames. Value is true if current matrices have been
cleared on at least one tty frame. This information is needed to
determine if more than one window has to be updated on ttys, whose
update requires building a frame matrix from window matrices.
This function is used where the old redisplay called
redraw_garbaged_frames which in turn called redraw_frame which in
turn called clear_frame. The call to clear_frame was a source of
flickering. I believe a clear_frame is not necessary. It should
suffice in the new redisplay to invalidate all current matrices,
and ensure a complete redisplay of all windows. */
