// offscreen context. |attrib_list| must be null or a NONE-terminated list
// of attribute/value pairs.
// If |surface| is not null, then it must match |is_offscreen|,
// |window| must be gfx::kNullAcceleratedWidget, and the command buffer
// service must run on the same thread as this client because GLSurface is
// not thread safe. If |surface| is null, then the other parameters are used
// to correctly create a surface.
