Before this commit, when running convert commands overlaying text on an image, ImageMagick would output the following warning:
convert: delegate library support not built-in '...' (Freetype) @ warning/annotate.c/RenderFreetype/1873
Even though text would render on the output image, the text looked pixelated. Adding fontconfig and freetype to ImageMagick fixes this.
