MJPEG Tools Svn

reduce the amount of whitespace (blank lines) in the usage summary so that
yuvdeinterlace's message isn't double/triple spaced (easier to read without
scrolling the window).

Fix slider related problem.
Add some shortcut keys to buttons.

cruft removal - neither libavifile or riffinfo .h files were used anywhere.

Since chanlist_names was 1) causing compilation problems with gcc4 and 2) is
not used anywhere in the mjpegtools sourcetree, it was deleted.

Added "-r 1 -w 13.333" and "-r 1 -w 24" to the list of radius/weight
combinations with efficient integer implementations.

Fix TOP_FORWARD and BOTT_FORWARD, so these work with chroma formats other than 4:2:0.

quick hack to support YCbCr 4:4:4, 4:2:2, 4:1:1.

NetBSD 2.0 support. Need a "-lossaudio" (NBSD 2 moved the sound to a sep lib)

Due to the 2 other patches compiling with -O6 works now again.
So I have enabled it.

added those 2 patches from the tracker:

Make jpeg-mmx build with gcc-3.4 -O3
