Large text size fail to draw border

[bhavin-chauhan]

Thanks for this custom text view. I have noticed that it was fail to render border or wrong border rendered when I try to set large font size(issue is Only in kitkat, works fine for 5.0 and up also works for Jelly Bean Os). I don't know it kind of android bug or not but I find out one link related to this.
