/********************************************************************************************
> BOOL BlendHelpers::BlendAttributes(BlendNodeParam * pParam, CCAttrMap* pBlendedAttrMap)
Author: David_McClarnon (Xara Group Ltd) <[email protected]> based on blender code
Created: 21/2/2000
Inputs: pParam - the blend node param
Outputs: -
Returns: TRUE if successful, FALSE otherwise
