 356     *
 357     *    "If program point size mode is enabled, the derived point size is
 358     *     taken from the (potentially clipped) shader built-in gl_PointSize
 359     *     written by:
 360     *
 361     *        * the geometry shader, if active;
 362     *        * the tessellation evaluation shader, if active and no
 363     *          geometry shader is active;
 364     *        * the vertex shader, otherwise
 365     *
 366     *    and clamped to the implementation-dependent point size range.  If
 367     *    the value written to gl_PointSize is less than or equal to zero,
 368     *    or if no value was written to gl_PointSize, results are undefined.
 369     *    If program point size mode is disabled, the derived point size is
 370     *    specified with the command
 371     *
 372     *       void PointSize(float size);
 373     *
 374     *    size specifies the requested size of a point.  The default value
 375     *    is 1.0."
 376     *
 377     * The rules for GLES come from the ES 3.2, OES_geometry_point_size, and
 378     * OES_tessellation_point_size specifications.  To summarize: if the last
 379     * stage before rasterization is a GS or TES, then use gl_PointSize from
 380     * the shader if written.  Otherwise, use 1.0.  If the last stage is a
 381     * vertex shader, use gl_PointSize, or it is undefined.
 382     *
 383     * We can combine these rules into a single condition for both APIs.
 384     * Using the state point size when the last shader stage doesn't write
 385     * gl_PointSize satisfies GL's requirements, as it's undefined.  Because
 386     * ES doesn't have a PointSize() command, the state point size will
 387     * remain 1.0, satisfying the ES default value in the GS/TES case, and
 388     * the VS case (1.0 works for "undefined").  Mesa sets the program point
 389     * mode flag to always-enabled in ES, so we can safely check that, and
 390     * it'll be ignored for ES.
