I got the 96 dpi working too!
I got a SYS from Ankit360 and it worked like a charm. No problem at all. Actually i don't use any kitchen as such, had built my own batch scripts that automate the process a bit, i guess that's why i was getting problems. I downloaded the SYS that was made for PPCKitchen i think.
Anyways, i have noticed one change in this build apart from this theme API change. The TreeView control has been made finger friendly. The + sign against each item is bigger and there is lot of space between consecutive items. You can watch this in action in apps like Advanced Configuration Tool etc.
Just thought someone here might find the fact interesting
