+ * Computes the feature colour for a given sequence and column position,

+ * The graphics argument should be provided if transparency is applied
+ * (getTransparency() < 1). With feature transparency, visible features are
+ * written to the graphics context and the composite colour may be read off
+ * from it. In this case, the returned feature colour is not the composite
+ * colour but that of the last feature drawn.
+ * <p>
+ * If no transparency applies, then the graphics argument may be null, and the
+ * returned colour is the one that would be drawn for the feature.
+ * <p>
+ * Returns null if there is no visible feature at the position.
+ * <p>
+ * This is provided to support rendering of feature colours other than on the

+ * Note this method takes no account of whether the sequence or column is
