It is not possible to define additional environment variables

[nadiamoe]

For certain use cases it is beneficial to be able to set arbitrary environment variables for the X11 session. For example, setting QT_SCALE_FACTOR is a very convenient way to make the browser bigger on small touchscreens.

However, I haven't found so far a way to do this other than manually editing .xinitrc, which as per the comment on the file is strongly discouraged.

A way to do this would be to allow .xinitrc to source, instead of exec, /var/lib/chromium-kiosk/chromium-kiosk-prehook.sh. This way, the prehook would retain its current functionality but also allow exporting env vars which would persist in the X session.

As a workaround, I've managed to do this by dropping export lines on /var/lib/chromium-kiosk/.bashrc, as it happens to be sourced by .bash_profile in the same directory.

However as it seems that the latter is on its path to be deprecated (#71) I think the issue is still valid.

.xinitrc should still work after #71 is done, so maybe source chromium-kiosk-prehook.sh as suggested? and be done with it? PR's welcomed

I have added EXTRA_ENV_VARS option to config, see docs
