TIFFWriteEncodedStrip/TIFFWriteEncodedTile: fix rewriting of LZW-compressed data 
Fixes https://github.com/OSGeo/gdal/issues/1439

When rewriting a LZW tile/strip whose existing size is very close to a multiple of
1024 bytes (and larger than 8192 bytes) with compressed data that is larger,
the new data was not placed at the end of the file, causing corruption.

9cfa5c4691 tiffcrop.c: fix invertImage() for bps 2 and 4 
too much bytes were processed, causing a heap buffer overrun
    http://bugzilla.maptools.org/show_bug.cgi?id=2831
the loop counter must be
    for (col = 0; col < width; col += 8 / bps)

Also the values were not properly calculated. It should be
255-x, 15-x, 3-x for bps 8, 4, 2.

But anyway it is easyer to invert all bits as 255-x = ~x, etc.
(substracting from a binary number composed of all 1 is like inverting
the bits)

tiff2ps: fix heap-buffer-overflow 
http://bugzilla.maptools.org/show_bug.cgi?id=2834

usually the test (i < byte_count) is OK because the byte_count is divisible by samplesperpixel.
But if that is not the case, (i + ncomps) < byte_count should be used, or
maybe (i + samplesperpixel) <= byte_count
