Resolved merge conflicts: - lib/Epub/Epub.h: Kept both upstream's cropped parameter and HEAD's thumb functions - lib/JpegToBmpConverter/JpegToBmpConverter.cpp: Used upstream's version (dithering code moved to BitmapHelpers) - src/activities/home/HomeActivity.cpp: Kept HEAD's comment about stack size Added missing 1-bit dithering support to BitmapHelpers: - Added Atkinson1BitDitherer class to BitmapHelpers.h - Added quantize1bit() function to BitmapHelpers.cpp
