[Tracker] [PATCH] extractor-jpeg: fix original resolution conversion

[lionel g landwerlin linux intel com]

From: Lionel Landwerlin <lionel g landwerlin linux intel com>

According to the specification (http://www.exif.org/Exif2-2.PDF),
the resolution unit is described as :
 2     = inches unit
 3     = centimer unit
 other = reserved
