Re: [PATCH 4/4] Only report multi-touch when pen is out of range

I don't see why we should filter out multitouch while the pen is in range. There are many reasons why it might be useful to support simultaneous pen and touch. For example, use one finger to select a color to draw with and use the pen in the other hand to draw. Jeff. On Thu, Jul 7, 2011 at 2:05 PM, Jason Gerecke [off-list ref] wrote:

Don't bother evaluating multi-touch packets from the hardware when the pen is in range. Single-touch is already filtered, but not MT.
