[WebGLVis] Rec-Preview-Image ratio

[PeterHasitschka]

Images with different height and width are shown distorted.

Best solution would be, if a proxy server could be used for

• cropping images to a square
• acting as a CORS-Server allowing Cross-Reference-Call (Providing Access-Control-Allow-Origin: * in its header)

Client side solutions are not so easy in Three.js
Would need to paint image source on a canvas with some offsets etc. followed by creating a Texture from it.

@gerwald do you see possibilities to set up such a service somewhere?
