g3d conflict HRICS surfaces
Bug introduced by Pull request #690
The drawing of the surfaces (HRICS) causes unwanted side effect on other drawing (e.g. transparency of Graph)
The bug seems to be actually related to an integration issue between HUD and the surface display. (using each one separately is ok, but both creates the bug)
reproducing the bug:¶
enable HUD and its agent info, init GTP  and HRICS, refresh the screen (e.g. by moving the cam) : the names above the agents have a strange apperance.
You can also display a graph after doing some MP, the graph will have the same look.
: with drawing of surfaces enabled, no tested with pr #736
