            Description

            OCR programs do a pretty cool job at capturing text but layout can be a little different then a document that was type set for print. If the page is when scanned is slightly skewed the text coordinates will reflect the skew.

            Our code for detecting spaces and line breaks wasn't designed for the text that might slowing move vertically from the start of a line to the ends.

            This bug will capture changes needed to improve word and line detection and work ordering.
