Wallpaper Positioning, More Fine-Grained Zoom Percentage, and the ability to have local files with .css embeds.

[KingKrouch]

Hello, I figured I'd point out some things that I feel like this plugin could improve:

• The ability to change the vertical position of a wallpaper from the settings GUI. For example, if I had an HTML page that is designed for a 16:9 aspect ratio, and it zooms in to fit it all on the screen, there's no way to change the vertical position of what's being drawn.

• One current issue is that using a local file is quite limited in terms of .css and .js stuff that you can run, because of the CORS policy. For example, if I wanted a Spine2D/Live2D viewer that's local (for an HTML live wallpaper that the Wallpaper Engine plugin for KDE Plasma doesn't support yet), I would have to run a local http server using python -m http.server where the index.html is first, and then put http://localhost:8000 into the address section. Could there be some sort of way to automate this, using some sort of port that only the plugin can access?

• Some more fine-grained zoom controls would be a nice feature to have.
