Subject: Project assignment misconceptions

(This message is being sent to all CPSC 101 section 302 students)

Please remember that in mirror_ppm_pixel() that there are TWO
images that are in use.  Your mission is to COPY a pixel value
to the OUTPUT image from the appropriate location in the INPUT
image... A couple of students have used the term "swap" which
WOULD be correct IF the mission was to transform a SINGLE image
into a mirror of itself --- but thats NOT THE PROBLEM.
