[FIX] Lag fix for cm10 based roms (cm10, paranoid android, jellybro) (4.1 only)

---

I have a fix for the lagginess in builds from the past week and a half or so. The culprit is the surface flinger library. It is the android compositing system and some changes recently made to it are responsible for the significant lag in recent builds. Most noticeable spot is if you hit the home button if you have the notification drawer down. It becomes extremely laggy without this patch. Scrolling is also less smooth whenever multiple things on the screen are being drawn. This fixes all those issues.

Just flash this in cwm or whatever recovery you choose. Should work on all cm10 builds and cm10 based roms like paranoid android.

HELL YEAH! I can see the improvement all over - thank you for this! I was "putting up with it" (read: thinking I needed, but too lazy to do a full wipe) and BAM! Fixed. Thanks!

Does it work on CNA?

Would it work for the Sourcery rom?

Yup this is only for cm10 based ROMs. I think aokp may have ruled the bad library as well from cm so you can try it on that as well.

I would but I still haven't found the exact change on gerrit that caused the issue. My patch just uses the library from an older build. I think the only change between the two libraries is the one that causes the lag. This is really my first major fix in have found if someone wants to help me track down the exact spot in the source code that needs to be reverted I would really appreciate it. Still kind of new at this.

I don't know if sourcery is aokp or cm based.
