Refactoring autoScaleUp with zoom to scaleUp
Browse files Browse the repository at this point in the history 
This commit contributes to the renaming of methods DPIUtil.autoScaleUp
containing int zoom as an argument to DPIUtil.scaleUp, since the scaling
is not done automatically but based on the zoom level which is provided.

Contributes to #62 and #127
