 422     *    "If program point size mode is enabled, the derived point size is
 423     *     taken from the (potentially clipped) shader built-in gl_PointSize
 424     *     written by:
 425     *
 426     *        * the geometry shader, if active;
 427     *        * the tessellation evaluation shader, if active and no
 428     *          geometry shader is active;
 429     *        * the vertex shader, otherwise
 430     *
 431     *    and clamped to the implementation-dependent point size range.  If
 432     *    the value written to gl_PointSize is less than or equal to zero,
 433     *    or if no value was written to gl_PointSize, results are undefined.
 434     *    If program point size mode is disabled, the derived point size is
 435     *    specified with the command
 436     *
 437     *       void PointSize(float size);
 438     *
 439     *    size specifies the requested size of a point.  The default value
 440     *    is 1.0."
 441     *
 442     * The rules for GLES come from the ES 3.2, OES_geometry_point_size, and
 443     * OES_tessellation_point_size specifications.  To summarize: if the last
 444     * stage before rasterization is a GS or TES, then use gl_PointSize from
 445     * the shader if written.  Otherwise, use 1.0.  If the last stage is a
 446     * vertex shader, use gl_PointSize, or it is undefined.
 447     *
 448     * We can combine these rules into a single condition for both APIs.
 449     * Using the state point size when the last shader stage doesn't write
 450     * gl_PointSize satisfies GL's requirements, as it's undefined.  Because
 451     * ES doesn't have a PointSize() command, the state point size will
 452     * remain 1.0, satisfying the ES default value in the GS/TES case, and
 453     * the VS case (1.0 works for "undefined").  Mesa sets the program point
 454     * mode flag to always-enabled in ES, so we can safely check that, and
 455     * it'll be ignored for ES.
