If for nothing else, to permit them to be used as the basis for the manual
creation of similar parts, and abstraction into resuable sub-components. Not a
strong reason, but worth considering.

To use just one example - the STUD primitive : stud.dat.
Using this allows renderers to :
- include the LEGO logo, reduce the sharpness of the upper edge, convert to a
true cylinder, thus improving the image quality.
- substitute the low-quality stud replacement (stu2.dat), or even just a line
thus reducing render time for draft renders
- buffer highly repetitious components thus reducing render time

I don't think we should limit the LDraw library to users with state-of-the-art
PCs - not all users have 80Gb disk drives. But disk storage space is not the
only issue - larger files and a larger library means longer download times, and
not everyone is on high-speed broadband.
