Why do the textures need to be this width and height?

Hello, I have a question.
I've been looking into your code and honestly it's pretty amazing that you're able to display .dds compressed textures in the browser! But why do these textures have to be 128128, 256256, etc. ?
I'm a modder for a video game called "Hearts of Iron IV", which uses the .dds fromat as general image compression. But most of those images do not have this "power of two" width and height.

Would it be possible to display those not power of two images in my browser?

I'd really like to implement or at least help to implement your .dds file preview into the Github Desktop software (which almost all big mods for Hearts of Iron use to sync their files in their team).
