Detailed Description

Table of colors at regular value positions.

You usually create the table from a Sequence and a Mapper. The Mapper::seqPosition() and Sequence::color() calls can be quite costly. For standard jobs involving a lot of data you cannot afford that. So, you need to pre-calculate a fixed number of exact colors and snap to those, or, if you can want to and you can afford it, interpolate. So, you use this class.

The indexFor() and getColorAt() functions do not check on undef or rubbish being passed. Check this yourself and take appropriate action. You can pass values outside the range though (returns first or last index or color).
