TAlignmentPatternFinder Class

This class attempts to find alignment patterns in a QR Code. Alignment patterns look like finder patterns but are smaller and appear at regular intervals throughout the image.

At the moment this only looks for the bottom-right alignment pattern.

This is mostly a simplified copy of {@link FinderPatternFinder}. It is copied, pasted and stripped down here for maximum performance but does unfortunately duplicate some code.

This class is thread-safe but not reentrant. Each thread must allocate its own object.

Unit: ZXing.QrCode.Internal.AlignmentPatternFinder

This method attempts to find the bottom-right alignment pattern in the image. It is a bit messy since it's pretty performance-critical and so is written to be fast foremost.
