- For well-defined, high-level errors we prefer to not wrap them with
stacktraces if the stacktraces add little value. It just makes it more
labor-intensive to handle those errors effectively (especially
external ones).
- These are absolute representations of where an IFD is positioned with
respect to the other IFDs. There is a more-specific, "fully-qualified"
form of the IFD-path that allows you to express indices in order to
refer to specific siblings.
- Eliminates issues with IFDs at different levels potentially having the
same name (if that's what is required with a certain dataset/
datasource).
- There is a specific IFD registry that controls the heirarchy of IFDs
that we recognize and the tags associated with the child IFDs. This
allows custom hierarchies replacing even the TIFF specification for
which are expected in an image (so we can read other types of images
or any potential IFD hierarchy, even non-image ones).
- IFD and IB instances embed the IFD-path and FQ IFD-path that they were
found or built for.
- We're prepping to deimplement IsExif() because it's just a lame
duplication of ParseExifHeader().
- Transitional step to being able to fix incorrect-header problem.
- Updated IfdByteEncoder tests to use it instead of hacking-together
their own BT's (makes for more standardized, consistent testing).
- Universally refactored all core IFD knowledge implemented upon a
single IFD name to instead work with IfdIdentity instances, instead,
in order to validate that we only recognize the IFDs only in the
context of the correct parents in the hierarchy.
- Implemented standard testing byte-order (assigned to
TestDefaultByteOrder).
- Added some assertions and constants. Renamed from variable so it'd be easy to
tell if the byte-arrays, even though they come directly from the EXIF, which
specific offsets they start at (so no remove for confusion during enumeration
and building).
