Subject: Additional sp2 requirments

(This message is being sent to CPSC 215 Students and TA's)

A student asks:

I have no requirements regarding things like format of variables
names and location of { characters. Variable names should be
reasonably indicative of their use in the program though.

More detailed standards will be announced for the raytracer.
For the short programs please use these:

1 - All programs when compiled with -Wall must produce NO WARNINGs.

2 - Source code lines must not exceed 75 characters in length.

3 - Reasonable commenting must be provided.  The sp1.c solution
    is an example of what I consider reasonable.

4 - For sp2.c pointer notation (instead of array notation) must
    be used to read/write pixel data.  (You may leave the array
    notation in the .ppm header reading code).
