This update for librsvg fixes the following issues:

- CVE-2018-1000041: Input validation issue could lead to credentials leak. (bsc#1083232)

Update to version 2.40.20:

+ Except for emergencies, this will be the LAST RELEASE of the
librsvg-2.40.x series. We are moving to 2.41, which is vastly
improved over the 2.40 series. The API/ABI there remain unchaged,
so we strongly encourage you to upgrade your sources and binaries to
librsvg-2.41.x.
+ bgo#761175 - Allow masks and clips to reuse a node being drawn.
+ Don't access the file system when deciding whether to load a remote
file with a UNC path for a paint server (i.e. don't try to load it at all).
+ Vistual Studio: fixed and integrated introspection builds, so
introspection data is built directly from the Visual Studio project
(Chun-wei Fan).
+ Visual Studio: We now use HIGHENTROPYVA linker option on x64 builds,
to enhance the security of built binaries (Chun-wei Fan).
+ Fix generation of Vala bindings when compiling in read-only source
directories (Emmanuele Bassi).

Update to version 2.40.19:

+ bgo#621088: Using text objects as clipping paths is now supported.
+ bgo#587721: Fix rendering of text elements with transformations (Massimo).
+ bgo#777833 - Fix memory leaks when an RsvgHandle is disposed before
being closed (Philip Withnall).
+ bgo#782098 - Don't pass deprecated options to gtk-doc (Ting-Wei Lan).
+ bgo#786372 - Fix the default for the "type" attribute of the element.
+ bgo#785276 - Don't crash on single-byte files.
+ bgo#634514: Don't render unknown elements and their sub-elements.
+ bgo#777155 - Ignore patterns that have close-to-zero dimensions.
+ bgo#634324 - Fix Gaussian blurs with negative scaling.
+ Fix the <switch> element; it wasn't working at all.
+ Fix loading when rsvg_handle_write() is called one byte at a time.
+ bgo#787895 - Fix incorrect usage of libxml2. Thanks to Nick Wellnhofer
for advice on this.
+ Backported the test suite machinery from the master branch (Chun-wei Fan,
Federico Mena).
+ We now require Pango 1.38.0 or later (released in 2015).
+ We now require libxml2 2.9.0 or later (released in 2012).
