bugfixes: last 3 lines not brightness/contrast corrected

	brightness statistics messed up with initial black pic
changed initial values of the brightness statistics
C++ -> C conversation
QP range question solved (very likely 1<=QP<=32 according to arpi)
new experimental vertical deblocking filter
RK filter has 3dNow support now (untested)

 reduce the time wasted on the mem transfer
 implement dering
 implement everything in C at least (done at the moment but ...)
-figure range of QP out (assuming <256 for now)
 unroll stuff if instructions depend too much on the prior one
 we use 8x8 blocks for the horizontal filters, opendivx seems to use 8x4?
 move YScale thing to the end instead of fixing QP
 write a faster and higher quality deblocking filter :)
+do something about the speed of the horizontal filters
