* Just removing a header file would cause build errors with no hint as
to what happened. This way, people get a warning rather than error
for the life of qpdf 11, and the warning tells them what to do.
* This avoids build surprises resulting from having two versions of
QPDF headers installed at once. If you were building code out of a
checkout of qpdf but had an older version installed on your system,
if your code included <qpdf/QPDFObject.hh>, everything would work,
but then your code would break without QPDFObject.hh later.
Also, modify QPDFObject::swapWith to update the ObjGens of the swapped
objects.
Modify QPDF::newIndirect and QPDF::updateCache to keep object ObjGens
up to date.
Allow QPDFObjectHandle::obj to be set prior resolving object.
ot_unresolved has been appended to the list object types in order to
preserve the output of existing test cases.
This comment expands all tabs using an 8-character tab-width. You
should ignore this commit when using git blame or use git blame -w.
In the early days, I used to use tabs where possible for indentation,
since emacs did this automatically. In recent years, I have switched
to only using spaces, which means qpdf source code has been a mixture
of spaces and tabs. I have avoided cleaning this up because of not
wanting gratuitous whitespaces change to cloud the output of git
blame, but I changed my mind after discussing with users who view qpdf
source code in editors/IDEs that have other tab widths by default and
in light of the fact that I am planning to start applying automatic
code formatting soon.
They have to be ot_* rather than qpdf_ot_* for compatibility.
* Different enumerated types are not assignment-compatible in C++, at
least with strict compiler settings
* While you can do `constexpr ot_xyz = ::qpdf_ot_xyz` in QPDFObject.hh to
make QPDFObject::ot_xyz work, QPDFObject::object_type_e::ot_xyz will
only work if the enumerated type names are the same.
Change object type Keyword to Operator, and place the order of the
object types in object_type_e in the same order as they are mentioned
in the PDF specification.
Note that this change only breaks backward compatibility with code
that has not yet been released.
