srowen 869ddc1dbf Improvement to finder/alignment pattern detection in low-res situations: use averages. It makes it much better on images of this sort, decreasing failure rate by about 60%. (It makes one old image fail, but looks like a fluke)

dswitkin 395f145067 Deleted the old ean13-2 test data which contained high resolution blurry images. These are not the focus of ZXing and not worth testing against. I'm going to replace them shortly with more relevant test images.

dswitkin 5cc1df3c92 Finished work on the local binarizer and renamed it to HybridBinarizer. It uses the old histogram for 1D and the new approach for 2D. The unit tests don't fully demonstrate how much better this is in real-world lighting, but it pretty much solves the situation of pointing at a QR Code for 30 seconds without scanning, due to a shadow or gradient. 
HybridBinarizer is now the default across all the fast clients and the unit tests.

dswitkin 01eed5266e - Converted parts of the PDF 417 reader to use BitMatrix. 
- Changed the PDF 417 detector to search the image more broadly, instead of assuming the barcode starts in the left 1/4 and ends in the right 1/4. We now get 8/23 on the real-world blackbox test, and we'll probably do even better with further improvements here.
- Added a quiet zone to two of the unit test images and updated a golden result for one of them. We now get 3/7 on the first test.
- Tried to fix some bugs in the upside down code but it still doesn't work.

dswitkin 1da9bd60b3 Added a new blackbox test with extreme shadows and highlights. We do pretty poorly on this, but I've been experimenting with local thresholding algorithms which are a night and day improvement. 
Also made the ImageConverter app ignore some kinds of files.

dswitkin c07fad6410 Created a new QR blackbox test with difficult exposures, mostly self-shadowing cases. We only get 34 out of 120 tests, which is about what I expected. To fix these we will have to move away from a global black point and towards a more sophisticated local thresholding algorithm.
