Multiple GifImageView's causing crash

[DanielSobczak]

Hi, when I was implementing your library I found out that I can't use GifImageView's in a ViewPager because it causing library to crash.

Here is the stacktrace

On my fork you can find code that is causing the crash, to reproduce it just launch app and scroll through ViewPager

I tested it on two devices (same result):

• Nexus 5 (6.0.1)
• Samsung Galaxy Note 4 (6.0.1)

OK, I'll investigate that.

That's because there were no strong/global references to byte buffers so they were garbage collected causing heap corruption.
Fixed in 1.2.8-SNAPSHOT.
Thanks for the report.
