srowen 15f34edb52 Simple check in Code 39 reader to determine wide bars vary in width a lot, to cut out most false positives

srowen 180e833b3e Improved approach to 1D decoding -- better use of integer math by scaling pattern ratios up to expected number of pixels, rather than the other way. Modified constants accordingly. Also introduced notion of maxium variance that any one bar in a pattern can have and stiill be accepted. Finally, adjusted false-positives test failure limit downward due to recent improvements.

srowen 2f9e5ca32b Fix pretty clear bug on Code 128 and 39 readers: reject empty barcodes as a false positive.

dswitkin 4d1229bd65 Created a library of images which do not contain barcodes, or contain barcodes we don't yet support. Wrote a new unit test designed to identify false positives, and set a benchmark which we can improve over time. Out of these 26 images, tested in all four rotations, we currently find 44/104 false positives. The Code 39 decoder in particular seems to be too lenient.

dswitkin f431cae59f - Added support for rotation in our blackbox test framework, and refactored the ways tests are created and run.
- Turned on 0 and 180 degree rotation for all 1D formats.
- Turned on 0, 90, 180, and 270 degree rotation for QR.
- Changed the 1D code to re-enable upside down scanning, with a dramatic improvement in barcodes found and fewer false positives.

dswitkin 0987663963 Added some simple sharpening for 1D decoding which allowed a couple more blackbox images to pass. There were a few cases where the format or content is now misdetected, but since the net gain was positive I decided to make those non-fatal errors. In real world use the sharpening seems to help, and I think we can do even better with a better algorithm.
