   It is better to a add public method which returns MultiResolution 
image on HiDPI display and  consists of two resoltion variants
    - base image which has size requested by a user
    - high-resolution image which creates an original screen capture

   The proposed by your algorithm can be applied to the base image.
   For more details see JDK-8020618 [macosx] java.awt.Robot makes blurry 
screen captures on Retina
