I couldn't find a definite reference for the size of a MotionEvents history, when there are multiple pointers. The reference says that if you use a getHistorical* function, you might pass it a history position which is somewhere between [0..getHistorySize()-1]. But in a lot of examples handling multitouch if there are multiple pointers they only use history positions between [0..getHistorySize()/ getPointers()-1] (so they divide the history's size with the number of pointers). Which one is the correct way?
