the +-1 issue is limited to >2tap vertical filters, so bilinear upscale was unaffected
the new code is sometime faster sometimes slower but the difference is significant (~20%) so its optional and enabled with arnd=1

once when the scaler is initialized, instead of building them and freeing
them over and over. This gives massive performance improvements.

critical fixes by (Reza Jelveh <reza.jelveh at tu-harburg dot de>)
known bugs/issues, which should be fixed ASAP by someone who has a ppc:
0..255 vs. 16..235
unneeded recalculation of tables
general cleaup, like removing double initalizing of variables

x/yInc bugfix (bug was introduced during the global var removial)
more emms & no messing with ARCH_X86 (=workaround against not cleared mmx state somewhere)
sharpening filter (-ssf cs=<int> & -ssf ls=<int>)
Originally committed as revision 4298 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
-ssf cgb=<float> -> chrominance gaussian blur (nice to improve picture quality)
-ssf lgb=<float> -> luminance gaussian blur (dunno what its good for)
-ssf chs=<int> -> shift chrominance horizontally
-ssf cvs=<int> -> shift chrominance vertically
these will only work if the swscaler is used at all

dynamic memory allocation for the buffers (needed for the filter stuff)
Originally committed as revision 4291 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
experimental upscaling mode (-sws 3)
general convolution filters support (unfinished)
bugfix for bicubic upscaling
assertion checking if defined MP_DEBUG
checking of the input/output size instead of segfault if its very large

green lines in yuv2yuv scaler bugfix

someone who knows a bit about vo_odivx could add support for it ...
