I get a bunch of errors from imagemagic

1.) Regarding the fences the commands are like this:

convert blocks/planks_oak.png \( -clone 0 -crop 256x64+0+96 -rotate 90 -gravity center \) -composite /tmp/default_fence_wood.png

the source is 64x64. Why do we try to crop 256x64 with a 0x96 offset if the source is 64x64. A command like

convert blocks/planks_oak.png \( -clone 0 -rotate 90 -gravity center \) -composite /tmp/default_fence_wood.png

works fine. What if we extract a function to create the fences to avoid the code duplication and then check the sizes first.

If this is also a case of a bad theme, it would be awesome if you could add a link to what these reference you use to the README. I've been looking at e.g. http://minecraft.gamepedia.com/Resource_pack

Could be an ImageMagick version problem. The IM commands change per version, and often in an incompatible way. Maybe just change the code in the way that works for you and PR that?
