srowen 14e22bd443 Revamp the character encoding detection to use a more complicated but still crude algorithm that detects more Shift_JIS sequences correctly.

dswitkin a8b57c466d Discovered that our 1D Readers were being reallocated for every row scanned - yikes! I made them reusable across both rows and different scans. This saved 26 ms on the worst case rejection. We can now consistently reject any 240x240 image on Android in 150 ms or less, checking all 7 formats.

dswitkin bf362ae853 Added 17 new, unusual QR Codes to the blackbox tests. We can decode the majority OK, but some of the contents are not agreeing with the golden results because of a text encoding issue.

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.

dswitkin 1d8b533310 Fixed the Android client when using ProGuard. The ViewfinderView constructor is loaded dynamically by the XML view inflation code, which requires explicitly preserving it.

dswitkin 4f7b7d573d Made the data members of BitArray public so they will be inlined. This saves about 60,000 function calls per rejected scan. We can make these private again once we figure out the ProGuard problems with -allowaccessmodification.

dswitkin 43e155804f Looks like -allowaccessmodification to ProGuard results in a bogus binary. It compiles, but the Dalvik verifier rejects it at runtime. I'm removing this flag for now, which means we lose inlining on some important getters and setters.

dswitkin 1e478df248 Added androidtest to the top-level clean target and set it up for ProGuard too. Made both Android builds depend on clean so they work when switching between normal and ProGuard builds, and made install and reinstall use the latest binary instead of recompiling.

dswitkin d80cd07064 Made a change to the QR detector which cuts the worst case rejection time from 300 ms to 160 ms, with almost no penalty in decoding ability. Given that we're emphasizing continuous decoding, I feel it's much better to reject the occasional borderline image in half the time, and get on with the next scan.

dswitkin de419268b8 Wrote a benchmark activity for Android which reads images recursively from the SD card, decodes each 10 times, and prints the average time to decode in milliseconds. The UI is extremely minimal, as the results are written to the log, but this is a good start towards measuring our performance under Dalvik on a platform without floating point hardware. This should run fine on the emulator but I haven't tested it yet.

dswitkin 8cb804ec9e Made a change to 1D decoding which looks for 100% instead of 150% of the start and end patterns when searching for quiet zones, but in exchange for that reduction, we reject rows whose quiet zones would run off either edge of the image.
The result is complete elimination of all false positives in the new batch of 40 images I just checked in. Bettter than that, we come up with a net gain of 38 new barcodes decoded (counting rotation and try harder variations). We even get some of the reflective images that were impossible up to this point.

dswitkin edcf34f0c5 Created 40 new blackbox images which are partial shots of a very large QR code. In mobile mode we do OK, but in try harder we find bogus 1D results in almost half of these. I'm checking this in as a baseline, and will work on improving the situation in a subsequent change.

dswitkin c91f427a8b Added a bit of defensive programming in the AlignmentPattern code. There were real world examples where the width passed to AlignmentPatternFinder was zero, which causes BitArray to throw when built with a size of zero. I'm going a little bit farther and not searching extremely small areas either.
