commit d7b8d97fd5259decb94d553e34c263cdff8ebf22

evas events: Add "raw" x,y values for future extensions
For pen tablets, this exposes the values as given by the driver
(quite useless without knowledge of the device itself).
For mice, this exposes x,y as set by the display manager, without
any extra processing in terms of smoothing or prediction. IOW
this returns the same as x,y until a smoothing algorithm is
implemented (todo).
