Bug#581902: iceweasel: Sufficiently large images displayed incorrectly; cut off after ~32k pixels?

Package: iceweasel
Version: 3.6.4~build2-1
Severity: normal

In doing some data analysis, I needed to work with some images of size
6000x$BIGNUM.  I found that beyond a certain size, Iceweasel would start
cutting off the bottom of the image.  Judging by the scrollbar position,
32k seems likely, which would make sense.

I've attached a 6000x50000 grayscale PNG, large enough to demonstrate
the problem but still small enough to reasonably email.  The bright line
in the image should form a smooth curve, but it just stops after a
while.

Note that even larger images seem to hit some internal limit past which
Iceweasel seems to consider them corrupt and refuses to even display
them; I'll report that as a separate bug.
