Version 3.0
-----------
1. Support for surfaces has been added using the cagd_lib library (see
cagd_lib documents for more). A new '-f FineNess' flag has been added to
support subdivison fineness.
2. A much simpler parser has replaced the existing one. The new parsing (and
new text fromat) is much easier and faster, and obviously support free
form surfaces/curves as well (see cagd_lib from more).
3. The '-o Objects' object has been taken out.
Version 2.0
-----------
1. Anti aliasing using super sampling and simple box filter has been added.
Always set current color intensity, and ignored the background color, as
we are very limited with the number of colors we have (256).
2. Program has been ported to Unix system and compiled under:
a. BSD4.3, using gcc.
b. Iris 4d, Irix 3.2, using cc.
