Subject: [PATCH] Create a desktop-entry for st
Enables to find st in a graphical menu and to display it with a nice
icon.
If some applications still are not displaying an icon for st try the patch
[netwmicon](../netwmicon/). Programs like tint2 and alttab rely on a hardcoded
icon which has to be stored by st in the \_NET\_WM\_ICON window-property.

commit 0663bdf11a409961da5b1120741a69814da8ce65
Author: Timo Röhling <timo@gaussglocke.de>
Date: Tue Nov 23 19:45:33 2021 +0100
Terminal scrollback with ring buffer
This patch adds a ring buffer for scrollback to the terminal. The
advantage of using a ring buffer is that the common case, scrolling with
no static screen content, can be achieved very efficiently by
incrementing and decrementing the starting line (modulo buffer size).
The scrollback buffer is limited to HISTSIZE lines in order to bound
memory usage. As the lines are allocated on demand, it is possible to
implement unlimited scrollback with few changes. If the terminal is
reset, the scroll back buffer is reset, too.
