Remove image test of dell laptop.

It was large, slowed the tests down and didn't really have much

Tests: update 'oracle' images and add one

Fix broken placement of rectangles, they didn't need to be offset by

The 'oracle' images were created with broken alignment; rectangles were
offest by several pixels.

Also, add a new test that's meant to check exact alignment (concentric
shapes).
