Modified shadowmap calculations to include multipass for point lights. Added shader funtions to calculate point light shadows. Added getter for default znear and zfar values in Graphic3d_Camera. Added direction and up vector calulations on Graphic3d_CubeMap. Added logical exception for opengles2.0 lack of support on some key features of cube shadow maps. Added test case.
