SDPose: resize fix

[kijai]

• Fix model input orientation. head.heatmap_size follows MMPose's (W, H) convention, which was matched wrong for pytorch (H, W)

• Switch resize from bilinear to area

• Stretch resize instead of aspect ratio preserving pad, as the model is trained like that, gives expected accuracy on harder images.

📝 Walkthrough

Walkthrough

In comfy_extras/nodes_sdpose.py the SDPose preprocessing was corrected: model_w is now taken from head.heatmap_size[0] and model_h from head.heatmap_size[1]. _resize_to_model was changed to stretch images to (model_h, model_w) and return separate horizontal/vertical scales (sx, sy). _remap_keypoints was updated to use scale_x/scale_y with x/y-only remapping. Call sites were adjusted for the new return values and signature. In CropByBBoxes, common_upscale was switched from bilinear to area for both resize paths.
