DMagick image processing with D.

[Andrej Mitrovic]

sigmoidalContrast.d works, although draw.d doesn't:

Magick: unable to read font `@ghostscript_font_path at n019003l.pfb' @
error/annotate.c/RenderFreetype/1120.

I guess displaying is only possible via X server? Otherwise I guess I
could fetch the raw bytes of the image and display that via GDI/etc.
I've seen a toBlob function in there somewhere, maybe I can use that.

I've never used this lib before but it will definitely come in handy.
Thanks for your hard work, Mike!
