/* minimum alignment rules ;)

* If you notice errors in the align stuff, need more alignment for some ASM code
|
|
* for some CPU or need to use a function with less aligned data then send a mail
|
|
* to the ffmpeg-devel mailing list, ...
|
|
*
|
|
* !warning These alignments might not match reality, (missing attribute((align))
|
|
* stuff somewhere possible).
|
|
* I (Michael) did not check them, these are just the alignments which I think
|
|
* could be reached easily ...
|
|
*
|
|
* !future video codecs might need functions with less strict alignment
