Broken implementation of the Acid2 test.

The Acid2 test is a test of web browsers to see if they can show parts of the internet correctly. It uses CSS and HTML to put things in the right places. It uses the PNG format for the images it uses in the test. A company's web browser that works with the Acid2 test is able to show most of the internet correctly and is a modern web browser.
