comfyanonymous 13e6d5366e Switch clip vision to manual cast.
Make it use the same dtype as the text encoder.

Implement Self-Attention Guidance (#2201)
* First SAG test

* need to put extra options on the model instead of patcher

* no errors and results seem not-broken

* Use @ashen-uncensored formula, which works better!!!

* Fix a crash when using weird resolutions. Remove an unnecessary UNet call

* Improve comments, optimize memory in blur routine

* SAG works with sampler_cfg_function

comfyanonymous fbdb14d4c4 Cleaner CLIP text encoder implementation.
Use a simple CLIP model implementation instead of the one from
transformers.

This will allow some interesting things that would too hackish to implement
using the transformers implementation.

comfyanonymous 61a123a1e0 A different way of handling multiple images passed to SVD.
Previously when a list of 3 images [0, 1, 2] was used for a 6 frame video
they were concated like this:
[0, 1, 2, 0, 1, 2]

now they are concated like this:
[0, 0, 1, 1, 2, 2]
