CATROID-181 Fix issue where visual placement jumps after panning

[ndrnour]

Visual placement sometimes incorrectly jumps object to finger position after careful panning to another position.

Please take the time in account. E.g. SystemClock.elapsedRealTime()

very helpful, thanks

Please move the onTouch behavior into a separate, unit testable class as discussed personally

done, but without test (sorry), because I couldn't understand the way of Mockito

LGTM now 👍

As discussed yesterday face to face.

IMO this fixes the issue described in the ticket. I talked to @ndrnour and I think if there is anything else to do we should do it as another separate ticket.

I implemented what I could and saw right. I missed one part regarding ignoring the last 100 ms.
if you really need this to be implemented please please let someone else work on it.
I already spent much time on this. I want to work on something else.
thanks for understanding.

Thanks a lot, and I fully understand ;-) there are many more things to add to the visual placement, and yes, someone else can take over --- sorry for being so nitpicking!!!
