just a frame on vector basis, textured with the plugin on the background. So you are stretching only the texture on this, in fact, no deep programming, or manipulation with the code of badly programmed (or missing support) nonHiDpi plugin needed. You take only its envelope, (the plugin projection to the screen) … and strech this on a frame. Yes, you will get some artifacts, but on HiDPI it will have almost the same blurriness as on NonHiDPI setting. It is like a video, stretched on a frame of any MediaPlayer. Even you don’t have 4K, or HD source, you can stretch your LQ video on fullscreen of a 4K monitor.
