18 tickit_window_get_pen() returns a pointer to the given window's pen
19 instance. This pen instance is directly stored by the window. The
20 application is permitted to modify this pen instance, though any modi‐
21 fications will not be observed until the window is next exposed for
22 rendering.
23
24 tickit_window_set_pen() stores a new pointer for a pen instance into
25 the given window. The window retains a reference to that pen and incre‐
26 ments the reference count on it. Any previous pen is unreferenced
27 first.
28
29 Because the window stores what may be one of many references to the pen
30 instance, applications that do modify the pen should be careful that
31 such modifications do not adversely affect other users of the same pen.
32
34 tickit_window_get_pen() returns a pointer to a pen instance.
35 tickit_window_set_pen() returns no value.
