Drawing HiDPI component to BufferedImage

[Alexander Scherbatiy]

  Hi Hendrik,

  The API that allows to create custom images for HiDPI displays is only 
under discussion now.
  It can be found in the thread: 
http://mail.openjdk.java.net/pipermail/awt-dev/2014-January/006775.html
  It also contains a link to the patch that allows SunGraphics2D class 
to correctly draw multi-resolution images.

  You can try to apply the patch to the JDK 9 and check that it works 
for your case.

  Thanks,
  Alexandr.

Unfortunately, this technique does not work well on Retina/HiDPI displays, as I can't seem to be able to convince any components to render in high resolution to a BufferedImage.
