Release iText 7.1.6

iText 7.1.6 is the sixth maintenance release for iText 7.1 Core/Community. We're also updating the add-ons pdfHTML to 2.1.3pdfCalligraph and pdfSweep to 2.0.4.

SVG support was greatly improved in this release. We now support elliptical paths, S/s and T/t commands for relative/absolute smooth cubic and relative/absolute smooth quadratic Bézier paths, and SVG transparency is also now supported.

In total, about 60 tickets were closed, many of which were of significant complexity.
