the question about min_bounds and max_bounds setting of xtfont3.c/xtfont4.c/xtfont6.c in xts5

Hi all,

In vsw5, there is a switch for min_bounds and max_bounds values in
xtfont3.c,
xtfont4.c and xtfont6.c. It checks whether XT_X_RELEASE is 6.

/* from xtfont6.c */
XFontStruct xtfont6 = {
      (XExtData*)0,
      (Font)0,
      FontRightToLeft,  /* direction */
      0,    /* min_byte2 */
      255,  /* max_byte2 */
      0,    /* min_byte1 */
      1,    /* max_byte1 */
      0,    /* all chars exist */
      2,    /* default char */
      3,    /* n_properties */
      props,
      {-16, -16, -16, -1, -10, 0},
#if XT_X_RELEASE == 6
        {-2, 0, -3, 11, 3, 0},
#else
        {0, 0, 0, 11, 3, 0},
#endif
      perchar,
      11,   /* font ascent */
      3,    /* font descent */
};
/* end */

If so, the following case will fail to run:

/tset/Xlib9/ldqryfnt/Test 1 FAIL
/tset/Xlib9/lstfntswth/Test 3 FAIL
/tset/Xlib9/lstfntswth/Test 4 FAIL
/tset/Xlib9/qryfnt/Test 1 FAIL
/tset/Xlib9/qryfnt/Test 2 FAIL

If XT_X_RELEASE is set to other value except 6 when being built, they
can run successfully.

I searched about it on the web, but could not find any related information.
I also debugged into the source code of xorg, but still couldn't find any
behavior to explain why we do so.

Can anyone give me some guide?

Best Regards!
