Alpha component for text block doesn't seem correct

[Yan Cheng Cheok]

The entire text block ($10.0, $20.0) should be having same alpha component.

Far as I can tell, this is a 9patch issue... hmm.

It gets progressively more alpha.

I think that nine path was created wrong ... I will commit my version today, I hope ;)
