[Coco] reducing size of scanned magazines

[Aaron Wolfe]

I've uploaded the first 12 issues to maltedmedia.  Compared to the
high res scans they are about 10% of the size, but just as readable if
not better.  The ClearScan does a nice job, especially if you want to
be able to zoom in and out without losing clarity on the fonts.  It
turns the letters into sort of quasi vector things instead of bitmaps.
  I've also tried to reduce the bleed through in the background and
other tweaks where they seemed to help.
I am working my way through year 2 now.
