Fix bug #6364 with slow scrolling on MS-Windows with bitmap fonts.

 src/w32font.c (g_b_init_get_char_width_32_w): New static var.
 (globals_of_w32font): Zero it out.
 (GetCharWidth32W_Proc): New function pointer.
 (get_char_width_32_w): New function.
 (compute_metrics): If get_glyph_outline_w returns an error, try
 get_char_width_32_w before declaring a failure.  This avoids
 punishing raster (a.k.a. "bitmap") fonts by slowing down
 redisplay.
