Changes 9.10:
* Background printing (BGPrint) is a new feature allowing an accumulated page clist to be rendered by one or more rendering threads whilst the interpreter (in the "main" thread) continues to accumulate the subsequent page's clist. For certain classes of file this can result in a useful performance increase.
* GrayDetection allows suitably written devices to detect "color" input in near neutral tones (i.e. near monochrome) and to convert "on-the-fly" to pure grayscale, whilst retaining the ability to print full color on demand. This is primarily aimed at workflows where saving ink (especially color inks) is required.
* LittleCMS2 and libpng have both been updated to the latest versions.
* Support has been added to build the Ghostscript DLL for WinRT for x86, x64 and ARM (Requires MS Visual Studio 2012 Pro).
* Processing of Windows command line arguments into UTF8 (as presaged a few releases ago) has been enhanced and enabled by default.
* The URW Postscript font set has been updated to the latest version, fixing many compatibility problems with the Adobe fonts.
* Plus the usual round of bug fixes, compatibility changes, and incremental improvements.
