Emacs displays noisy black rectangles for XBM raw :data images.

;; wrong image is shown
(insert-image (create-image "\xff\x81\x81\x81\x81\x81\x81\xff"
                            'xbm t :width 8 :height 8))

;; correct image(8x8 pixel framed square) is shown
(insert-image (create-image "\
#define tmp_width 8
#define tmp_height 8
static char tmp_bits[] = {0xff,0x81,0x81,0x81,0x81,0x81,0x81,0xff};"
                            'xbm t))
