// "HybridImageView" is a subclass of NSView that displays a single image, centered and unscaled over a solid background.  The image to be displayed can be a CIImage or an NSBitmapImageRep.  If it is a CIImage, the view will draw itself using OpenGL for better performance.  If it is an NSBitmapImageRep, the view will draw itself using Cocoa/Quartz APIs.  An instance of HybridImageView switches automatically between OpenGL and Quartz rendering depending on the type of image it is given to display.

@interface HybridImageView : NSView

{

    id                  image;              // the CIImage or NSBitmapImageRep to display

    NSOpenGLContext     *openGLContext;     // the NSOpenGLContext we use to draw the image if it is a CIImage

    NSOpenGLPixelFormat *pixelFormat;       // an NSOpenGLPixelFormat used to create the NSOpenGLContext

    CIContext           *ciContext;         // the CIContext we use to draw the image if it is a CIImage

    NSColor             *backgroundColor;   // background color used to fill the area behind the image

}
