* Source/cairo/CairoGState.m: Added code in -drawGradient:

Browse source 
fromPoint:toPoint:options: to handle gradients for colorspaces
	other than NSCalibratedRGBColorSpace, NSDeviceRGBColorSpace,
	NSCalibratedWhiteColorSpace, NSDeviceWhiteColorSpace,
	NSCalibratedBlackColorSpace, NSDeviceBlackColorSpace.  The
	previous implementation assumed RGB based colorspaces only.
