Fixed bug dealing with div height.

Changes:
 * Fixed formatting of @AlmogBaku's code from his pull request (4-space
   tabs)
 * There was a bug where, when the window was resized, the div and its
   background image (the original floated image) would have their height
   set incorrectly. This is fixed.
 * Added version number to the top of the file.
 * Adjusted copyright year to 2012
 * Fixed spelling of "potatoes" :-)
 * Added radix parameter to the padding `parseInt` calls.
If object is hidden do not wrap it!
