images with one dimension < 256 are neon noise

[ssube]

Setting the image size to < 256 in one or both dimensions causes the image to be a mess of neon noise:

256x256 works just fine, as do most sizes above that, such as 256x384 or the default 512x512.

I'm not sure if this is a normal limitation of the SD v1.5 net or an issue with the latents or something else entirely.

After more testing, 256x256 doesn't appear to be working correctly either. All of the literature I can find says that the intended output is supposed to be 512, 1024, or 768 for certain specific models: https://huggingface.co/stabilityai/stable-diffusion-2/discussions/22

I will adjust the minimum size sliders to prevent this. For now, smaller images can be downsampled after generating them. I may add an option for that in the client.
