The change doesn't affect the bitstream. It changes the order or function
calls and affects how we reconstruct intra- and inter-blocks. Speed up is
about 1...1.5%.
For intra-blocks:
Before:
for each transform block read tokens
for each transform block do prediction
for each transform block do inverse transform
Now:
for each transform block
read tokens
do prediction
do inverse transform
For inter-blocks:
Before:
for each transform block read tokens
for each transform block do inverse transform
Now:
for each transform block
read tokens
do inverse transform
