Make fluid wallpaper transparent, transparent.

The "BG Transparent" option in Fluids V2 just changes the background to a bunch of squares

It would be good if the squares were replaced with your pre-existing wallpaper, if you could add a "BG Transparent" option to the others like Fluids V2 then you could change the mountain with a burger for example, that would be really cool.

You will have to edit the webpage code and change the texture to custom image file.
Optionally use Folder dropdown control to change the file during runtime.

Thanks, I am a bit confused about the "Folder dropdown" control but I will try changing the webpage code.
