Overhaul image, imagesc to use newplot and support low-level invocation form.
* scripts/image/image.m: New variable do_new indicates high-level calling form.
For high-level invocation, call newplot before __img__. Correct linearity check
if vectors are reversed (high-to-low values). Only apply image properties to axes
if doing a high-level invocation.
* scripts/image/imagesc.m: New variable do_new indicates high-level calling form.
Delete subfunction __imagesc__ and incorporate minimal amount of code into imagesc.
Only apply climits for high-level invocation.
