2019-06-21	Fix sign and conversion warnings (major)	Jay Berkenbilt
	This makes all integer type conversions that have potential data loss explicit with calls that do range checks and raise an exception. After this commit, qpdf builds with no warnings when -Wsign-conversion -Wconversion is used with gcc or clang or when -W3 -Wd4800 is used with MSVC. This significantly reduces the likelihood of potential crashes from bogus integer values. There are some parts of the code that take int when they should take size_t or an offset. Such places would make qpdf not support files with more than 2^31 of something that usually wouldn't be so large. In the event that such a file shows up and is valid, at least qpdf would raise an error in the right spot so the issue could be legitimately addressed rather than failing in some weird way because of a silent overflow condition.
2018-06-21	Convert examples to use new page helper classes	Jay Berkenbilt

2017-08-22	Spell check	Jay Berkenbilt

2017-08-21	Enhance pdf-create example	Jay Berkenbilt
	pdf-create now creates images with different color spaces and encoding schemes and verifies them for data correctness.
2013-03-04	Remove all old-style casts from C++ code	Jay Berkenbilt

2012-07-21	Implement QPDFObjectHandle::parse	Jay Berkenbilt
	Move object parsing code from QPDF to QPDFObjectHandle and parameterize the parts of it that are specific to a QPDF object. Provide a version that can't handle indirect objects and that can be called on an arbitrary string. A side effect of this change is that the offset used when reporting invalid stream length has changed, but since the new value seems like a better value than the old one, the test suite has been updated rather than making the code backward compatible. This only effects the offset reported for invalid streams that lack /Length or have an invalid /Length key. Updated some test code and exmaples to use QPDFObjectHandle::parse. Supporting changes include adding a BufferInputSource constructor that takes a string.
2012-07-07	Don't require stream data provider to know length in advance	Jay Berkenbilt
	Breaking API change: length parameter has disappeared from the StreamDataProvider version of QPDFObjectHandle::replaceStreamData since it is no longer necessary to compute it in advance. This breaking change is justified by the fact that removing the length parameter provides the caller an opportunity to simplify the calling code.
2012-06-27	Add QPDFObjectHandle::newStream(QPDF *, std::string const&)	Tobias Hoffmann
	This makes the code simpler than having to create a buffer of a fixed size and copy the string to it.
