sound: Ensure to preserve sound theme when changing from default
The sound theme change itself triggers signals that are handled here
in the GSettings handlers, possibly resulting in it changing the
theme back to default. Ensure we are handling a real change here,
the sound theme will be updated through other means (eg. the row
changed handler).
A GTK bug (also fixed in that MR) prevents the tool id from updating.
Until that GTK bug is fixed the pen will only be detected if it is the first
event from this physical device. If the touch node sends an event before the
pen, the pen won't be detected.
The xf86-input-wacom driver doesn't use 0 for tools that do not have an id or
serials. Serials default to 1, and the tool id is either 0x2 for stylus or 0xa
for eraser, see xf86WacomDefs.h, the defines for STYLUS_DEVICE_ID and
ERASER_DEVICE_ID.
libwacom uses 0xfffff and 0xffffe for the generic pens and all the lookup code
we have in the panel is designed for a serial/tool id of 0. So let's just map
the wacom driver IDs to 0 at the only transition point between Gdk and our
panel.
No devices with serials 0 or hw ids 2/10 exist, so this shouldn't have side
effects. This only affects X + xf86-input-wacom.

user: Support devices with more than 5 enroll steps
We are currently adding support for Synaptics devices that require 8
steps. Add another row for images which brings us to up to 10
supportable steps for now.
