CoglRenderernew

Instantiates a new (unconnected) CoglRenderer object. A CoglRenderer represents a means to render. It encapsulates the selection of an underlying driver, such as OpenGL or OpenGL-ES and a selection of a window system binding API such as GLX or EGL.

There are also some platform specific configuration apis such as cogl_xlib_renderer_set_foreign_display() that may also be used while the renderer is unconnected.

Once the renderer has been configured, then it may (optionally) be explicitly connected using cogl_renderer_connect() which allows errors to be handled gracefully and potentially fallback configurations can be tried out if there are initial failures.

If a renderer is not explicitly connected then cogl_display_new() will automatically connect the renderer for you. If you don’t have any code to deal with error/fallback situations then its fine to just let Cogl do the connection for you.

Once you have setup your renderer then the next step is to create a CoglDisplay using cogl_display_new().
