Subject: Add support for XI 2.4
X-Git-Tag: emacs-29.0.90~3464
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=71eb1aac54e2143d40c16a9f67e76200f63e6561;p=emacs.git

Add support for XI 2.4

We will be able to use touchpad (not touchscreen) gestures, such
as pinch and swipe gestures after this change, but they are not
yet exposed to Lisp.

* src/xterm.c (x_term_init): Declare support for XI 2.4 if
present.
