Use nearest neighbor interpolation when resizing watermarks. #4

I can't work on this myself at the moment but I noticed that resized watermarks don't look so great due to the transparency being resampled and causing really horrible looking transitions. Perhaps forcing an interpolation method that doesn't "blur" the transparency would fix this, such as nearest neighbor. Just a thought.

Do you have an example image to test with?

I tested with some images and some resolutions. Results are ok.
