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 167197ec7a Refactored the MonochromeBitmapSource class hierarchy into LuminanceSource, Binarizer, and BinaryBitmap classes. The unit tests pass and I believe the change is complete, but there are some clients like J2ME and Bug that I can't build. 
This change will allow new thresholding algorithms to be developed and tested, as well as implemented per platform if needed (e.g. in JNI on Android). It should also perform better when multiple 2D Readers are installed, because the underlying image will only be converted to 1 bit once. It also allows some platforms to return luminance data without a copy.

The current state of this checkin is to use the old black point algorithm, which now lives in GlobalHistogramBinarizer. This will be our benchmark and fallback for slower platforms. Going forward we will begin to use LocalBlockBinarizer as I shake out the edge cases and tune it for performance. Currently it is unused.

IMPORTANT: I have temporarily included three methods from MonochromeBitmapSource at the end of BinaryBitmap as a way to make this change in stages. They are deprecated and will be removed soon. All of the Reader classes will need to change the way they examine 1 bit pixels to use the new getBlackRow() and getBlackMatrix() calls.

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 0a4e715ae4 Extended the command line tool to dump the results of black point calculation. You can now use the flag --dump_black_point to generate a PNG which contains the original image, the row scanning monochrome version, and the 2D scanning monochrome version side by side. It will be saved as originalfilename.mono.png.

dswitkin e19e9a83f6 I moved a chunk of the histogram/black point code out of BaseMonochromeBitmapSource and into BlackPointEstimator which makes a lot more sense. Unfortunately I had to expose three new methods and touch a bunch of files. But I did manage to reuse an array on subsequent calls, which was being allocated on every row scanned, so that might be a bit faster. It will also be easier to convert this code to JNI in the future if we want to, and/or do more advanced thresholding.

dswitkin 8671371c59 Did a big refactoring on the MonochromeBitmapSource. I removed all the caching luminance calls and converted them to getting luminance data on demand. This saved another 33,000 function calls per rejected scan, good for another 15 ms savings. I also moved the luminance calls to BaseMonochromeBitmapSource and made them protected, to indicate that the decoders shouldn't use them. 
Overall the recent optimizations took one rejected scan from 307 to 135 ms, which is definitely noticeable.

WARNING: I am not able to build the Bug or J2ME clients, but I believe they are correct.
