BasicMultiGPUSample

===================================================================================

DESCRIPTION:

This sample demonstrates what an OpenGL application should do to detect possible 

renderer changes. When running on a multi-GPU system, in order to render the OpenGL 

content correctly on all hardware, your application needs to be able to detect 

renderer changes. Whenever the virtual screen changes, the capabilities of the video 

card you are currently rendering to can change, so you must re-query those capabilities

(such as max texture size) and adjust your drawing paths as necessary to support 

the newly active GPU.

This sample demonstrates how to detect and respond to renderer changes in both 

an NSOpenGLView subclass and an NSView subclass. It also demonstrates how to enable 

the usage of offline renderers (renderers that are not connected to a display).

PACKAGING LIST:

MyNSOpenGLView.h/.m

This is an NSOpenGLView subclass. Demonstrates how to detect and respond to 

renderer changes if you are using an NSOpenGLView subclass.

MyOpenGLView.h/.m

This is an NSView subclass. Demonstrates how to detect and respond to renderer 

changes if you are not using NSOpenGLView.

BoingRenderer.h/.m

This class handles the rendering of a Boing ball using Core Profile. This class 

does not contain code relevant to multi-GPU support.
