Color is interpolated between the startColor and endColor along the given
vector (starting at the origin, ending at the terminus).  If no vector is
supplied, it defaults to (0, -1) -- a fade from top to bottom.

If 'compressedInterpolation' is disabled, you will not see either the start or end color for
non-cardinal vectors; a smooth gradient implying both end points will be still
be drawn, however.

If ' compressedInterpolation' is enabled (default mode) you will see both the start and end colors of the gradient.
