From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Jeremy Apthorp <jeremya@chromium.org>
Date: Wed, 10 Oct 2018 15:07:34 -0700
Subject: command-ismediakey.patch

Override MediaKeysListener::IsMediaKeycode and associated functions to also listen for
Volume Up, Volume Down, and Mute.

Also apply electron/electron@0f67b1866a9f00b852370e721affa4efda623f3a
and electron/electron@d2368d2d3b3de9eec4cc32b6aaf035cc89921bf1 as
patches.
