The public interface of vgl, generated from its headers. vgl's stable ABI is the C API; the C++ wrapper (the .hpp headers, namespace vgl) is header-only on top of it.

Header	Contents
`vgl/vgl.h`	Includes every core header
`vgl/base.h`	Results, version, vectors and matrices, export macros
`vgl/foundation.h`	Allocator, logging, I/O and task interfaces
`vgl/geodesy.h`	Ellipsoids, geodetic and ECEF coordinates, ENU frames
`vgl/context.h`	The context: packs, views, updates, queries, statistics, attribution
`vgl/render.h`	The render interface: frames, resources and draw lists
`vgl/defaults.h`	Thread pool, file reader, HTTP reader and disk cache
`vgl/gl.h`	OpenGL / OpenGL ES backend
`vgl/d3d11.h`	Direct3D 11 backend
`vgl/ogre.hpp`	Ogre 14 backend (C++ only)

The conventions behind the API are in the C API conventions and the render interface specification; the integrator's guide explains how to use them.
