Log Message:
-----------
Added very basic calls to impliment the heat-graph. This will be lightmodel 8,
and will
eventually determine how much time was spent calculating each pixel during a
raytrace.
After the initial raytrace is completed, the picture will be replaced with a
graphical
representation of how long each pixel took in regards to the entire picture,
where
short times are charactarized as one color, and transition to another color
representing a longer time.
However, now it just changes the background to white.
