alternative from mk/jpeg.buildlink3.mk
This allows selection of an alternative jpeg library (namely the x86 MMX,
SSE, SSE2 accelerated libjpeg-turbo) via JPEG_DEFAULT=libjpeg-turbo, and
follows the current standard model for alternatives (fam, motif, fuse etc).
The mechanical edits were applied via the following script:
#!/bin/sh
for d in */*; do
[ -d "$d" ] || continue
for i in "$d/"Makefile* "$d/"*.mk; do
case "$i" in *.orig|*"*"*) continue;; esac
out="$d/x"
sed -e 's;graphics/jpeg/buildlink3\.mk;mk/jpeg.buildlink3.mk;g' \
-e 's;BUILDLINK_PREFIX\.jpeg;JPEGBASE;g' \
< "$i" > "$out"
if cmp -s "$i" "$out"; then
rm -f "$out"
else
echo "Edited $i"
mv -f "$i" "$i.orig" && mv "$out" "$i"
fi

* support for specifying resolution, size, orientation,
and placement of image
* support for JPEG 2000 image format
* options to force recompression of image data and to ignore pixel order
* support for EXIF Orientation tag (auto-rotate images)
* fix handling of interlaced GIF images
* LZW compression no longer optional (patent expired)
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
img2eps packages raster images into EPS (Embedded PostScript) files,
using whatever PostScript features are advantageous. If possible, the
compressed image data is copied directly to the EPS file.
Supported image file formats are GIF, JPEG, PNG, TIFF, and XPM.
