Shader Resolution Seems Low

[lonnietc]

Hello,

I was able to make things run just the Raymarching_Primitives.rs in a single window but while looking at the output, I see that the images appears to be low resolution (800x450) like on the shadertoys.com website.

I would expect that this could be improved since the Rust-GPU and Rust-GPU-ShaderToys projects run native but I do not know how to do it.

Any thoughts?
Thanks and Merry Christmas
