#351 xcode complains about -Wshorten-64-to-32 (mostly)

[Axel Waggershauser]

While working on the new zxing-cpp swift wrapper I ran into a bunch of warnings that you might or might not want to address (based on the 2.16 release):

• WARN | [zxing-cpp/CBridge] xcodebuild: zxing-cpp/core/src/libzint/raster.c:1390:36: warning: variable 'prev_image_row' may be uninitialized when used here [-Wconditional-uninitialized]

Thanks, suppressed the "-Wshorten-64-to-32" ones with commit [bd3395], but not the "-Wconditional-uninitialized" ones, at least not for now, as don't agree with it.
