Description (last modified by mlinkert)
Many .ndpi files contain JPEG streams that have a width and/or height larger than 65535 (the maximum size allowed in a JPEG stream). For images where (width * height) <= (65535 * 65535), we can solve the problem by setting an artificial width and height, then re-pack the tiles with the correct dimensions after they have been decoded.
For images with (width * height) > (65535 * 65535), though, we need a different strategy.

(In [de977aa84dffe5a14583689bfbd5d57703192290/bioformats.git]) Prevent errors for .ndpi files that use a DNL marker.
See #5092. The problem now is what to do about images which have a
width or height > 65535 (the maximum width and height allowed in a JPEG
stream).
