// The Ozone interface allows external implementations to hook into Chromium to
// provide a system specific implementation. The Ozone interface supports two
// drawing modes: 1) accelerated drawing using GL and 2) software drawing
// through Skia.
//
// If you want to paint on a window with ozone, you need to create a GLSurface
// or SurfaceOzoneCanvas for that window. The platform can support software, GL,
// or both for painting on the window. The following functionality is specific
// to the drawing mode and may not have any meaningful implementation in the
// other mode. An implementation must provide functionality for at least one
// mode.
//
// 1) Accelerated Drawing (GL path):
//
// The following functions are specific to GL:
//  - GetAllowedGLImplementations
//  - GetGLOzone (along with the associated GLOzone)
//
// 2) Software Drawing (Skia):
//
// The following function is specific to the software path:
//  - CreateCanvasForWidget
//
// The accelerated path can optionally provide support for the software drawing
// path.
//
// The remaining functions are not covered since they are needed in both drawing
// modes (See comments below for descriptions).
