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

- Added DLCAPS_ALPHA_RAMP: Alpha values for formats with one or two alpha
bits can be chosen, i.e. using ARGB1555 or ARGB2554 the user can define
the meaning of the two or four possibilities. In short, this feature
provides a lookup table for the alpha of these formats.
- Added DLCAPS_PREMULTIPLIED indicating that a display layer
can display surfaces with premultiplied alpha.
- Added DSCAPS_PREMULTIPLIED indicating that the surface has
premultiplied alpha data.
- Added DLCONF_SURFACE_CAPS and field 'surface_caps' to DFBDisplayLayerConfig
to specify any combination of the flags: DSCAPS_INTERLACED, DSCAPS_SEPARATED
or DSCAPS_PREMULTIPLIED.
- Added DLCAPS_SCREEN_POSITION and DLCAPS_SCREEN_SIZE.
These are set if DLCAPS_SCREEN_LOCATION is set and vice versa.
Unscalable layers just have DLCAPS_SCREEN_POSITION.
- Added DSECAPS_BRIGHTNESS, DSECAPS_CONTRAST, DSECAPS_HUE, DSECAPS_SATURATION.
- Added DSECONF_ADJUSTMENT to DFBScreenEncoderConfigFlags.
- Added 'DFBColorAdjustment adjustment' to DFBScreenEncoderConfig.

- Initial version of a Radeon DirectFB driver featuring solid drawing/filling
and simple blitting with or without key by Michel Da"nzer <michel@daenzer.net>.
- Added VT switching support which has to be enabled via option "vt-switching".
It's pretty well working already, though there are some minor issues left.
- Added support for multiple multi application worlds with new option
"session=<num>" selecting the multi application world being joined or created.
VT switching between multiple DirectFB sessions rocks!
- Added option "primary-layer=<id>" to swap the primary with the specified one,
this way all applications can be started on the second head (Matrox).
- Added "dfblayer", a display layer configuration tool (for multi app).
- Added IDirectFB::GetInterface() to load interface modules like "IFusionSound".
- Added time stamp to DFBWindowEvent.
- Quitting the master (first multi app process) sends SIGTERM to all slaves
and waits for them to quit (with a timeout).
- Core systems (currently FBDev and SDL) are dynamically loaded as modules,
which prevents DirectFB from being linked against SDL if support is enabled.
- Added window manager key 'E' to focus the window under the mouse cursor.
- Moved all global variables of the software driver to a new struct resulting
in a major increase of primitive throughput, e.g. FillRectangle(1x1) by 16%.
- Enhanced tmpfs detection and added option "tmpfs=<dir>" to set it explicitly.
- Enhanced locking and safety in v4l video provider.
- Improved graphics primitive throughput up to 100% by saving locks.
- Added shared memory allocation tracking like for local memory.
- Modules and drivers are now binary compatible with single/multi app library.
- No more bone collector threads (3/master), almost instant object destruction.
- Other bug fixes and cleanups.

Add NetBSD to the list of supported platforms.
Changes:
0.9.18
------
- National Semiconductors Geode driver by Sarma Kolluru <Sarma.Kolluru@nsc.com>.
Great thanks to NSC for their support!!!
- nVidia Overlay support by Oliver Schwartz <Oliver.Schwartz@gmx.de>, currently
hard coded to XBox. For plain nVidia graphics adapter you need to change line
618ff of nvidia_overlay.c (uncomment line 618, comment out line 620).
- Added multi application support to SDL backend.
- Added triple buffering for display layers.
- Added DPMS support via IDirectFBDisplayLayer::SetScreenPowerMode().
...
DirectFB is a thin library that provides hardware graphics acceleration,
input device handling and abstraction, integrated windowing system with
support for translucent windows and multiple display layers on top of the
Linux Framebuffer Device.
It is a complete hardware abstraction layer with software fallbacks for
every graphics operation that is not supported by the underlying hardware.
DirectFB adds graphical power to embedded systems and sets a new standard
for graphics under Linux and BSD ( with SDL ).
