Bug #: 37563
Summary: Proofread Page maximum width for images generated from
djvu files

After removing the maximum image width with Bug 33613 there can be errors while
generating thumbnails. For example the djvu file [1] has the resolution of
5,664x7,140px. Generating thumbnails up to 3850px working fine, 3851px and more
causing an error [2]: "Error generating thumbnail Error creating thumbnail:
terminate called after throwing an instance of 'DJVU::GException' pnmtojpeg:
EOF / read error reading magic number". [3]
This is limited by $wgMaxShellMemory [4]. The extension must be calculate an
maximum width regarding to $wgMaxShellMemory. Perhaps the same for PDF files.
