Optimization

When a sequence is told to optimize itself, first it optimizes each transformation in the chain individually. Then it composes all the transformations into one KcsTechUCP transformation. Finally it uses that composed KcsTechUCP to do future evaluations. Overall optimization is provided with optimization and composition of the individual transformations in the list.

The KcsXformSeq class performs composition by asking each transformation in the list to compose. If none comply, it uses the base class method to compose. It attempts to compose from the rightmost to leftmost. By doing so, the harder-to-model devices (typically printers, which are on the right) get composed first.

If you request to optimize for size, KcsXformSeq detaches all of the original list. After optimizing for size, the only way to regenerate the original list is to build it again.
