55c9c01bec ModelSamplingFlux now takes a resolution and adjusts the shift with it. 
If you want to sample Flux dev exactly how the reference code does use
the same resolution as your image in this node.

comfyanonymous
5514c4b8ce Invert the start and end percentages in the code. 
This doesn't affect how percentages behave in the frontend but breaks
things if you relied on them in the backend.

percent_to_sigma goes from 0 to 1.0 instead of 1.0 to 0 for less confusion.

Make percent 0 return an extremely large sigma and percent 1.0 return a
zero one to fix imprecision.

This was broken because of recent changes so I fixed it and moved it from
the experiments repo.

43dcfcd754 Support lcm models. 
Use the "lcm" sampler to sample them, you also have to use the
ModelSamplingDiscrete node to set them as lcm models to use them properly.

4d21372152 Add: advanced->model->ModelSamplingDiscrete node. 
This allows changing the sampling parameters of the model (eps or vpred)
or set the model to use zsnr.
