Defining 'lineCase' in color interpolated line drawing routine, an integer
between 0 and 3 inclusive. I want to factor much of the code in the four
routines.

Finished with the color interpolated line drawing. Now it's time to factor the
code and optimize.

Implementing one more of the four color interpolation line drawing routines.

Making advancements on the color interpolated line drawing.

Starting to make major progress on refining the line drawing code.

Have something working for the color interpolated line drawing.

Making some progress on the fancier line drawing routine (3D). Updated some
test code previously; committing those as well.

Adding line clipper which does clipping of interpolated line colors.

Re-adding the drawLine() with color interpolation. We're going to do this.

Improving the performance of line drawing algorithm.
