Grid not aligned to image when window is resized

[GoogleCodeExporter]

Resizing the window will keep the background image centered while the grid for 
the keys is aligned with a set distance from the upper left corner.

On smaller screens this might become an issue (notebooks, netbooks).

Scrollbars or making the image and grid resize with the window would solve this.
