Wow, it's been 5 days!

OK, progress is as follows: I am implementing content.res & graphics classes. Yes, in parallel.
I've discovered and partly reversed that npTc PNG chunk, which holds nine patch information.
I've also finished reversing AXML. I am updating AxmlResourceParser now. So now I have only one value that I don't understand - that 0x00140014 flag(?) in START_TAG entry.
