The Dell Canvas exports 2 collections for the Pen part. The only
difference between the 2 is that the default one has half the resolution
of the second one.
The Windows driver switches the tablet into the second mode, so we should
behave the same.

Hi,
well, this is not the cleanest way of handling this mode set, but it is the
less intrusive AFAICT.
I was thinking that we might want to add a new field in struct wacom_feature,
but then it wouldn't make sense to keep the set mode specifics in
_wacom_query_tablet_data().
So I am open to any better suggestion, but this one works and the impact on
other HID generic tablets is null.
Cheers,
Benjamin
