d6a4c0b111 * some modifications to allow gcc to compile same code for -fPIC 
- introduced MOVQ_WONE, MOVQ_WTWO
* unrolled put_pixels_clamped_mmx
* added .baling where the jump address would be compiled on odd address
* added some testing code to disable all these routines (for time measurement)

e03c341ef3 - More work on preliminary bit rate control, just to be able to get an 
average variance for picture's MBs so we can adjust qscale on the MB layer.

37fbfd0a91 - Now the ME is done for the entire picture when enconding, the 
DCT/Quantization is done after we have calculated all the MV of the picture.
- This is the preamble for a better bit rate control.

80e103d04c PATCH by Rik Snel <rsnel@cube.dyndns.org> 
this patch enhances the jpeg header writer. It can be asked to omit
quantisation and huffman tables and it can write different horizontal and
vertical sampling factors. (the last thing is useless for libavcodec
itself (because libavcodec only handles YUV420P at ecoder level), but the
values are initialized so that operation of libavcodec is not impaired)
