[Ssc-dev] [guardianproject/SecureSmartCam] 28a0aa: Update to latest JpegRedactionLibrary

[Andrew Senior]

Hi everyone,
I have updated the jpegredaction branch of obscura cam to use the latest
version of the Jpeg-Redaction-Library which now allows a pixellation
redaction method (as well as solid grey and the original "copy strip"
method).
I would think that this makes it close to being a candidate for release and
would like to hear your thoughts on that and maybe have people start testing
it. (I've only done light testing on my Evo so far)

Limitations:
1) The resolution of the pixellation is fixed. it's 4 MCUs in x and y. In
many JPEG images this means the "macro pixels" are 64x64  pixels, but in
some it may be 32x32. Of course it should be in proportion to the size of
the region being redacted.
2) It doesn't support other redaction methods such as blur, overlay or
"crowd" (redact the background).
The latter should be easy to fix, the other two a bit more complex.
3) The branch may not have the latest fixes of obscurav1, though I synced a
couple of days ago.
4) In this version, an image selected from media is overwritten by the
redacted version (I think the gallery thumbnail isn't updated immediately) a
new photograph is written unredacted in 100MEDIA and redacted into CAMERA
directories.
