julia-vips

Messing about with julia to see what a libvips binding might look like.

Strategy:

We have a hierarchy of abstract types to represent the libvips type hierarchy
For each abstract type, there's a concrete mutable struct that subtypes (implements) it
We never use object.name, we always use getters and setters
We dispatch everything on the abstract types (except the implementations of the getters and setters, which use the concrete types)
Result: OO-style inheritance for the libvips class hierarchy, hopefully
