The loopback script did not set masked content to original after first loop. So each loop would apply a fill, or latent mask. This would essentially reset progress each loop.

The desired behavior is to use the mask for the first loop, then continue to iterate on the results of the previous loop.

- Improved user experience. You can now pick the denoising strength of the final loop and one of three curves. Previously you picked a multiplier such as 0.98 or 1.03 to define the change to the denoising strength for each loop. You had to do a ton of math in your head to visualize what was happening. The new UX makes it very easy to understand what's going on and tweak.
- For batch sizes over 1, intermediate images no longer returned. For a batch size of 1, intermediate images from each loop will continue to be returned. When more than 1 image is returned, a grid will also be generated. Previously for larger jobs, you'd get back a mess of many grids and potentially hundreds of images with no organization. To make large jobs usable, only final images are returned.
- Added support for skipping current image. Fixed interrupt to cleanly end and return images. Previously these would throw.
- Improved tooltip descriptions
- Fix some edge cases

Add correction file filename length limits on *nix systems

add progressbar to unipc sampler

initialize extra_network_data before use

Update ui_extra_networks.py

I updated it so that no error message is displayed when setting a webp for the preview image.

so eg if a two-letter or empty extension is used, `.txt` would break, this `max` call protects that.

force refresh tqdm before close

fix: gradio's ValueError about fetching extensions files

allow usage of latest fastapi

Use emojis for extra network buttons

Fix dims typo in unipc

Fix image generation on macOS 13.3 betas

add face restoration option to xyz_grid

feat: better lightbox when not enable zoom

Add a way for API txt2img and img2img requests to pass args to always on scripts

The test isn't working correctly on macOS 13.3 and the bool tensor fix for cumsum is currently always needed anyway, so enable the fix by default.

don't use emojis for extra network buttons; remove 'close'
