Subject: Re: [PATCH v2 0/4] input: synaptics - report correct width and pressure values

It was pointed out that I made a terrible mistake in 4/4 [1] of this series
and I'm going to fix it. But I have a question first.

Is there any reason why the pointer emulation takes care of ABS_PRESSURE,
but not ABS_TOOL_WIDTH?
I know for example that xf86-input-synaptics relies on both (at least the
current stable release) for the palm detection and there might be some
other userspace applications relying on it. If there's no specific reason,
I could include in this series the changes to make input-mt.c send also
ABS_TOOL_WIDTH.

Regards,
Gabriele
