Thanks, Alexandr. I wasn't necessarily looking for special images that support HiDPI. I just wanted to be able to draw a standard component (e.g. a JButton) to a BufferedImage in a way that causes the component to be rendered *as if* the given BufferedImage supported high resolution. Say the button is 16x16 pixels large in reg. DPI. Then I'd love to render the thing to a 32x32 BufferedImage in HiDPI. But other than rendering to the screen, there doesn't seem to be a way to convince the button that it should now render its HiDPI version.
