That's down to the person who implements it...

If the Graphics has no "in" or namespace, then it is resolved as it 
would be right now.
- if right now the LCL is searched before the other package =>it's 
finding it in the LCL
- if right now GraphicPkg is searched before the LCL => then the above 
is an error => as twice the same package is used.

"right now" => current implementation
