Questions about adjusting camera intrinsics in data augmentation #60

Thanks for the implementation of your awesome work.

I have a question about why the camera intrinsics of center crop is designed in this way. In your code, I think you only adjusted the focal length according to the size change by cropping, but why not consider the change in principal points and the scaling factor by rescale?

See #58. Also note that the Gaussian Splatting rasterizer only supports principal points at image centers.
