 It seems that my previous two replies can not be shown correctly. Let
 me paste them here:
 
 2nd:
 The previous patch does not distinguish the x-scroll and y-scroll.
 This patch fixes the bug.
 
 3rd:
 This one includes 2 patches. The scroll hack one is stable enough and
 not changed. The new one changes MuPDF's hard-coded DPI (72) with a X
 DPI detection (opens and closes a X Display within a function); this
 patch is not optional (since these is no need to keep the old way).
