 321     *     written by:
 322     *

 326     *        * the vertex shader, otherwise
 327     *
 328     *    and clamped to the implementation-dependent point size range.  If
 329     *    the value written to gl_PointSize is less than or equal to zero,
 330     *    or if no value was written to gl_PointSize, results are undefined.
 331     *    If program point size mode is disabled, the derived point size is
 332     *    specified with the command
 333     *
 334     *       void PointSize(float size);

 336     *    size specifies the requested size of a point.  The default value

 338     *
 339     * The rules for GLES come from the ES 3.2, OES_geometry_point_size, and
 340     * OES_tessellation_point_size specifications.  To summarize: if the last
 341     * stage before rasterization is a GS or TES, then use gl_PointSize from
 342     * the shader if written.  Otherwise, use 1.0.  If the last stage is a
 343     * vertex shader, use gl_PointSize, or it is undefined.
 344     *
 345     * We can combine these rules into a single condition for both APIs.
 346     * Using the state point size when the last shader stage doesn't write
 347     * gl_PointSize satisfies GL's requirements, as it's undefined.  Because
 348     * ES doesn't have a PointSize() command, the state point size will
 349     * remain 1.0, satisfying the ES default value in the GS/TES case, and
 350     * the VS case (1.0 works for "undefined").  Mesa sets the program point
 351     * mode flag to always-enabled in ES, so we can safely check that, and
 352     * it'll be ignored for ES.
