40: *
41: * A pane has two buffers attached, these are filled and emptied by the main
42: * server poll loop. Output data is received from pty's in screen format,
43: * translated and returned as a series of escape sequences and strings via
44: * input_parse (in input.c). Input data is received as key codes and written
45: * directly via input_key.
46: *
47: * Each pane also has a "virtual" screen (screen.c) which contains the current
48: * state and is redisplayed when the window is reattached to a client.
49: *
50: * Windows are stored directly on a global array and wrapped in any number of
51: * winlink structs to be linked onto local session RB trees. A reference count
52: * is maintained and a window removed from the global list and destroyed when
53: * it reaches zero.
