wallpaper engine how to add audio visualizer to live picture

Something else I noticed is that the sliders in the customise section give a wrong value if it is below 1 (for example 0.4 gives 4 and 0.3 gives 30000000000000000). In future its probably going to be based on Argument flag in LivelyInfo.json ( -system-audio, -system-nowplaying etc) In add wallpaper page file browser there is an option for 'Website Audio (*html)' which turns on audio processing. Its because you need to tell lively to turn on audio processing, when you drag and drop a html file lively assumes its a regular webpage so won't run it. even external program like Unity games etc.)

The preview is just the wallpaper application window itself being injected into lively window before sending to desktop as wallpaper (that's why it works across everything. So, I just resized them to the size of the previews created by lively. I implemented them, execpt the automatic generation of the preview, because the previews which are created are without the actual visualizer on it (I think the livelyAudioListener function isn't called in the preview window).
