For specific features of Livecode - as in the case of imagedata 
processing - such deterioration is not rare, but seems to be the 
standard in the development process. I suppose this is surely not 
intended, but rather a result of concentrating on more urgent features 
(not only from the perspective of the team) and thereby possibly 
neglecting the interrelatedness of newly added functions with existing 
ones. As Richard Gaskin recently aptly remarked, image processing is at 
present not a "sweet spot" in Livecode development.

I have described this in several of my recent posts, showing the 
continuing speed loss (and more severe side effects) from version LC 4.6 
through LC 7.  Depending on the complexity of the various scripts, image 
processing compared between 4.6 and 7 can be on the average 3 to 15 
times slower. LC 8 again adds another 10 to 20 percent to the poor 
performance of LC 7.

As a tolerable performance standard happened to exist in former versions 
of Livecode, it must be technically feasible to revert to at least such 
a standard (LC 4.6) without the need of extra funding in the new 
"Feature Exchange" program.

For the Feature Exchange program I could  think of improvements like to 
add Lua-functionality to Livecode image processing and the ability to 
use Photoshop-compatible filters. Thierry Douez has experimented with 
Lua externals (for Windows and Mac) as far back as 2010.
