optimize texture loading

I would like to make a feature requests regardings textures.

Would it be possible to let verge load low res textures at the beginning and load the full/high resolution afterwards? So for example in your glft normally texture01.jpg is applied. When the option load low res is set, verge tries to load every texture with the suffix “_low” so in the example “texture01_low.jpg”. Or maybe look for the same filename just in another folder. After the application is loaded verge is replacing the low textures with the normal ones in the background.

Second request:
The option to load webp images. This could share partly the same logic from the first request. If the browser supports webp, try to load .webp. If file can’t be found just stick with the original file type (jpg, png, etc.)
