Pinch zoom during pen mode doesnt work about android-quill HOT 4 OPEN

Unfortunately, no tablet seems to report any usable pressure information with 
capacitive pens. Only tablets with active stylus support report pressure that 
can be used for the "Quill" pen. I'll hide the quill icon on tablets without 
active stylus support in the future to reduce the confusion.

Gestures are disabled because the tablet can't distinguish between pen and 
fingers without an active stylus. So there is no way to distinguish drawing two 
points from a double-tap.

OK, but do you think it would be possible for tablets that don't support it to 
check if there is one or two fingers on the screen during pen mode? If there 
are two then zoom in/out (if there is a pinch) or pan/scroll around. If there 
is only one finger then draw.

These features would really set apart your app from the rest of the note taking 
apps because right now it is very inefficient to keep on selecting the panning 
tool every few words to just move the screen.

I made a slight modification to allow for long-click movement from pen/pencil 
mode for tablets where gestures are not recognized. It should not be too much 
more work to implement a method for pinch/zoom. If needed, I can send my 
modifications or work on this feature.

During pen mode, multitouch should move and scale the canvas. I would love your 
app so much more if you did this.
