As far as I can tell this part of the error is for the image_in variable of the resize function.

An ImageBuf was destroyed with a pending error message that was never
retrieved via ImageBuf::geterror(). This was the error message:
Could not initialize ImageBuf: the provided ImageSpec needs a valid width, height, depth, nchannels, format.
Cannot set_pixels() on an uninitialized ImageBuf

The only way I can replicate this is by creating an ImageBuf with at least one of the dimensions or channels set to 0, though I can't figure out how to cause that through texture projecting.
