Function GridGraph.CalculateDimensions
        
                CalculateDimensions
        
                (out int width, out int depth, out float nodeSize)
    
            
            Calculates the width/depth of the graph from unclampedSize and nodeSize.

        void CalculateDimensions (
out int  |     width  |         |
out int  |     depth  |         |
out float  |     nodeSize  |         
Calculates the width/depth of the graph from unclampedSize and nodeSize.
The node size may be changed due to constraints that the width/depth is not allowed to be larger than 1024 (artificial limit).
