Had a quick look at the failures. A few of them can be improved:

• regen test_acorr, test_image_interps without any text (remove_text)
• test_titletwiny can be rewritten to a non-image-comparison, just checking the title position, like test_titlesetpos which is just below it
• for test_hatching the text labels can probably removed? (can we generate legends with empty labels? not sure...)
