hello,

in the documentation for initWithCGLContext states that one can pass NULL for the colorSpace param so it defaults to the proper RGB colorspace: (from the QCRenderer class reference dev docs)
\
ColorSpace
A Quartz color space object. This must be an RGB color space. Pass NULL to use the default RGB color space. For more information on Quartz color spaces, see Quartz 2D Programming Guide.

The code below throws the error (also, patch vs composition? )

[QCRenderer initWithCGLContext:pixelFormat:colorSpace:patch:]: Argument "colorSpace" does not verify "(CGColorSpaceGetModel(colorSpace) == kCGColorSpaceModelRGB) && (CGColorSpaceGetType(colorSpace) != kCGColorSpaceDeviceRGB)"

(v001GLContext is an NSOpenGLContext)

v001Effects1Renderer =[[QCRenderer alloc]
					initWithCGLContext:[v001GLContext CGLContextObj]
					pixelFormat:[v001GLPixelFormat CGLPixelFormatObj]
					colorSpace: NULL
					composition: [v001CompositionTestLoader compositionAtIndex:0]
					];

Am I doing something wrong, are the docs wrong, or? I am trying to pass a cached QCComposition object. Thanks - more curious if this is a documentation issue, just reporting/asking for completeness sakes.
