Import graphics/zimg, a scaling, colorspace conversion, and dithering

The "z" library implements the commonly required image processing basics
of scaling, colorspace conversion, and depth conversion. A simple API
enables conversion between any supported formats to operate with minimal
knowledge from the programmer. All library routines were designed from
the ground-up with correctness, flexibility, and thread-safety as first
priorities. Allocation, buffering, and I/O are cleanly separated from
processing, allowing the programmer to adapt "z" to many scenarios.
