RGB colorspace does unpredictable thing

[doginthehat]

Been using this module to do fit to size cropped images and it works awesome.

The only problem I've had was the color space, it seems to create significantly different results from one machine to another - notably on one vps server with the latest imagemagick all the thumbnail colours were turning out way darker than the original's.

Switching the colorspace parameter from RGB to sRGB seems to fix the problem.
