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.

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.

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.

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.
