 372     *
 373     *    "If program point size mode is enabled, the derived point size is
 374     *     taken from the (potentially clipped) shader built-in gl_PointSize
 375     *     written by:
 376     *
 377     *        * the geometry shader, if active;
 378     *        * the tessellation evaluation shader, if active and no
 379     *          geometry shader is active;
 380     *        * the vertex shader, otherwise
 381     *
 382     *    and clamped to the implementation-dependent point size range.  If
 383     *    the value written to gl_PointSize is less than or equal to zero,
 384     *    or if no value was written to gl_PointSize, results are undefined.
 385     *    If program point size mode is disabled, the derived point size is
 386     *    specified with the command
 387     *
 388     *       void PointSize(float size);
 389     *
 390     *    size specifies the requested size of a point.  The default value
 391     *    is 1.0."
 392     *
 393     * The rules for GLES come from the ES 3.2, OES_geometry_point_size, and
 394     * OES_tessellation_point_size specifications.  To summarize: if the last
 395     * stage before rasterization is a GS or TES, then use gl_PointSize from
 396     * the shader if written.  Otherwise, use 1.0.  If the last stage is a
 397     * vertex shader, use gl_PointSize, or it is undefined.
 398     *
 399     * We can combine these rules into a single condition for both APIs.
 400     * Using the state point size when the last shader stage doesn't write
 401     * gl_PointSize satisfies GL's requirements, as it's undefined.  Because
 402     * ES doesn't have a PointSize() command, the state point size will
 403     * remain 1.0, satisfying the ES default value in the GS/TES case, and
 404     * the VS case (1.0 works for "undefined").  Mesa sets the program point
 405     * mode flag to always-enabled in ES, so we can safely check that, and
 406     * it'll be ignored for ES.
