PR Description

Fixes issue with zoomAndCenterAnimated do not center but zooms to the start of the graph. See issue #4334

In static method AnimatedZoomJob:getInstance added the assignment of the parameters zoomCenterX, zoomCenterY, zoomOriginX, zoomOriginY.

This is a tiny fix to this excellent library. The solution was suggested 4 years ago but noone created a PR. Please merge so me and others don't have to compile from source.
