+    Use deferred sorting with Dict again to avoid performance regression
+
+    This tries to move sorting a Dict into the first find call again,
+    but tries
+    harder to make the double-checked locking work correctly so that
+    at least
+    concurrent calls to find are correct (but concurrent calls to find and
+    add, set or remove are still not allowed).

+
+    Compile Qt5 frontend with -DQT_STRICT_ITERATORS
+
+    QT_STRICT_ITERATORS prevents conversion from non-const iterator to
+    const iterator.
+
+    It helps detecting situations where we waste resources due to
+    needless detach from implicitely shared container data (i.e. deep
+    copy).
+
+    If anyone should run into problems, they can disable strict iterators
+    using a global cache variable:
+
+    $ cmake DENABLE_QT_STRICT_ITERATORS=OFF [...]
+

+
+    Bugfix: Do not disregard Ref::gen when using Ref as a cache key
+
+    According to Leonard Rosenthol's book, the 'gen' field of a
+    reference is almost always zero.  However, this doesn't mean that
+    it can be ignored when comparing two Refs.
+
+    Incidentally, this patch also makes use of the recently introduced
+    Ref::operator<, which allows to replace the small custom class
+    ArthurFontID by a std::pair.

+
+    More review fixes
+
+    Text color is indicated by nonstroking color in graphics state
+            Assumption: Text rendering mode is 'fill'.
+
+    Increase color precision for lossless roundtrip of 16 bit integers
+            Our API takes QColor from user. We want to support a lossless
+            roundtrip
+            of QColor (16 bit per channel internally) through document
+            save and
+            load, and empirically found .5f is best match.
+
+    Check only .5f case of color channel roundtrip. Include 65535.
+            We check if precision == 5 is sufficient, and fail if not. We
+            know that
+            precision < 5 will never work, because target set contains
+            less numbers
+            than uint16 range.
+
+    Use smart pointer in textFont and textColor
+
+    Add test for CMYK QColor roundtrip
+
+    Support QColor::Cmyk to AnnotColor::colorCMYK conversion
+
+    Add simple test for font size. Fix actual/expected args.
+
+    Model font name as class Object, type objName
+            Take into account that ISO 32000 says Tf operand is always
+            an object of
+            PDF type "name". Further benefit: class Object introduces
+            ownership
+            semantcis.
+
+    Use more std::unique_ptr and fix some coding syle
+            Some places assumed ownership implicitely. Make it more
+            explicit.
+
+    Move parse/constructAppearanceString into DefaultAppearance
+            We gain cohesion and automatic memory management.
+
+    Fix minor styling issues
+
+    Use std::make_unique from C++14

+    SplashPath: Allocate temporary pathes on the stack
+
+    The majority of SplashPath'es are created using

+    i.e. with function scope.
+
+    Returning a SplashPath instead of a pointer from convertPath()
+    - which is cheap due to the move constructor - saves recurrent
+    new/delete's for each stroke/fill/... operation.

+Author: Adam Reichold <adam.reichold@t-online.de>
+Date:   Thu Aug 30 20:26:55 2018 +0200
+
+    Remove index out of range assertions from Array getters
+
+    A lot of code seems to have been incompatible with the recently
+    removed DEBUG_MEM
+    flag, i.e. it relied on the Array getters returning a null object
+    when the index
+    was out of range and rather checked the returned object type (since
+    they had to do
+    that in any case) than the index.
+
+    Due to this, debug builds became much harder to test, especially
+    using fuzzing. This
+    commit thereby removes the assertions to restore the situation when
+    DEBUG_MEM was
+    present but disabeld by default and should thereby fix oss-fuzz/10121.

+
+    Type 7 shadings are identical for PS and PDF, so we can just emit
