Thinking about the slider

After the first real-life tests on https://preview:joh316@stage.typo3.org we've seen that the old style of background images is hard to use in the new slider.

• Due to the slider buttons on the right, about 20% of the background image can't be used.
• The header, subheader and button are placed in the middle of the free place, so any text or objects on the background image are covered.

What do you think about, @fstein?
