* Change bf16 check and switch non-blocking to off default with option to force to regain speed on certain classes of iGPUs and refactor xpu check. * Turn non_blocking off by default for xpu. * Update README.md for Intel GPUs.
* Added initial support for basic context windows - in progress * Add prepare_sampling wrapper for context window to more accurately estimate latent memory requirements, fixed merging wrappers/callbacks dicts in prepare_model_patcher * Made context windows compatible with different dimensions; works for WAN, but results are bad * Fix comfy.patcher_extension.merge_nested_dicts calls in prepare_model_patcher in sampler_helpers.py * Considering adding some callbacks to context window code to allow extensions of behavior without the need to rewrite code * Made dim slicing cleaner * Add Wan Context WIndows node for testing * Made context schedule and fuse method functions be stored on the handler instead of needing to be registered in core code to be found * Moved some code around between node_context_windows.py and context_windows.py * Change manual context window nodes names/ids * Added callbacks to IndexListContexHandler * Adjusted default values for context_length and context_overlap, made schema.inputs definition for WAN Context Windows less annoying * Make get_resized_cond more robust for various dim sizes * Fix typo * Another small fix
