The DIB image format uses the 40 byte BMP header, followed by 3 masks
for RGB channels. We were reading 4 masks, consuming the first pixel
of the image.
Mostly fixes issue #1293. Remaining issue: alpha channel is actually a
transparency mask.

This is Christoph Gohlke's test suite from his personal PIL package found
at http://www.lfd.uci.edu/~gohlke/pythonlibs/.
This is just to bring it in as a separate commit. Future commits will align
it with Pillow.
