patch from Alex Fraser (z0r) eg. - vec.xyz = vec.zyx - vec.xy = vec.zw - vec.xxy = vec.wzz - vec.yzyz = vec.yxyx See http://en.wikipedia.org/wiki/Swizzling_(computer_graphics) made some minor modifications to this patch. tested access times and adding 336 attributes to vectors doesn't make a noticeable differences to speed of existing axis attributes (x,y,z,w) - thanks to python dict lookups.
