Oops, you're right. I forgot to test the leaf image, and with offset 70,
it actually crashes my device. However, with offset 20, I still get
pixel errors sometimes. I've now set it to 50 for the moment, and this
seems to work in all cases I've tried. 

But this still is a hack nevertheless.. especially when considering that
this code doesn't yet support images shorter than the screen width.

Thanks, a very good idea. I've pushed this to the repository, and I've
also moved the conversion from single bytes to uint32_t into the loading
routine. Should perhaps add a little bit more speed.

Again, please pull from the git repo and test.

Yours, Florian
