CYMK to RGB Conversion won't work when Magento Compiler is on

[jasperthedummy]

Pull request #14 (@rbrown) introduced support for CYMK images by converting them to RGB so that an image resize will not cause an image to become inverted in color. However, it doesn't work for sites using the Magento compiler, because the use of __DIR__ magic constant will point to [magento_root]/includes/src, instead of where the ICC profiles currently live [magento_root]/app/code/community/Varien/Image/Adapter/. The resulting resized image will still be inverted in color.

Suggestion to put the ICC files in [magento_root]/lib/FireGento/PerfectWatermarks/.

Afaik there is no advantage in using a compiler. But this is not my project, so I have no opinion in this.

I know many sites that are using the compiler, and many sites that don't. Just trying to make it compatible with everyone no matter what benefits the compiler may bring. Besides, /lib/ seems to be a more appropriate place to store external libraries.

Submitted a PR #17.
