 394     *    "If program point size mode is enabled, the derived point size is
 395     *     taken from the (potentially clipped) shader built-in gl_PointSize
 396     *     written by:
 397     *
 398     *        * the geometry shader, if active;
 399     *        * the tessellation evaluation shader, if active and no
 400     *          geometry shader is active;
 401     *        * the vertex shader, otherwise
 402     *
 403     *    and clamped to the implementation-dependent point size range.  If
 404     *    the value written to gl_PointSize is less than or equal to zero,
 405     *    or if no value was written to gl_PointSize, results are undefined.
 406     *    If program point size mode is disabled, the derived point size is
 407     *    specified with the command
 408     *
 409     *       void PointSize(float size);
 410     *
 411     *    size specifies the requested size of a point.  The default value
 412     *    is 1.0."
 413     *
 414     * The rules for GLES come from the ES 3.2, OES_geometry_point_size, and
 415     * OES_tessellation_point_size specifications.  To summarize: if the last
 416     * stage before rasterization is a GS or TES, then use gl_PointSize from
 417     * the shader if written.  Otherwise, use 1.0.  If the last stage is a
 418     * vertex shader, use gl_PointSize, or it is undefined.
 419     *
 420     * We can combine these rules into a single condition for both APIs.
 421     * Using the state point size when the last shader stage doesn't write
 422     * gl_PointSize satisfies GL's requirements, as it's undefined.  Because
 423     * ES doesn't have a PointSize() command, the state point size will
 424     * remain 1.0, satisfying the ES default value in the GS/TES case, and
 425     * the VS case (1.0 works for "undefined").  Mesa sets the program point
 426     * mode flag to always-enabled in ES, so we can safely check that, and
 427     * it'll be ignored for ES.
