// The geometry and tessellation link properties (GL 4.6 core table 23.35). Same shape as
// GL_COMPUTE_WORK_GROUP_SIZE above, and for the same reason: "a linked program object
// with a geometry shader" is one whose EXECUTABLE has the stage, so an
// attached-but-not-yet-linked shader must give INVALID_OPERATION rather than the previous
// link's value. The geometry three used to be listed here only to fall through into the
// INVALID_ENUM default, and the tessellation five were not listed at all.
