It's because they are not bitmap images. Instead, they use algorithms and points to determine where colour goes, so that you can infinitely zoom them nicely. A good example is a pdf. If you convert a word document to a pdf, the letters don't blurr no matter how far in you go. That's because pdf is a vector based filetype. However, they are an awful lot of trouble to create. I'd like to have a mod that would take MC screenshots (or make renders) that are in vector format. Another cool thing is that .svgs (standard vector filetype) is xml based, which means you can open the file in any random text editor. Further reading.
