Updated 0.9 demo

["Andrew D. Hwang" <ahwang@mathcs.holycross.edu>]

The current state of 0.9 is in the "usual place":

  http://mathcs.holycross.edu/~ahwang/software/epix-0.9.0rc1_src.tar.bz2

As before, this is an embryonic package without much friendly capability,
which installs in ~/epix-0.9. Points and vectors are in (I hope) their
final implementation, as is the "camera", the data structure used to
project from spatial coordinates to the screen plane. Labels partially
work, though the plan is that old code will eventually work with the
library, and it does not yet. There are five snippets of demo code in the
file "test.xp"; uncomment a #define statement to compile, and try tweaking
parameters to see how the camera works. Three of the demos were in the
last posted version, but they've been re-written to work with the current
package.
