Different image scaling strategy

I was getting OOM with decodeByteArray on large images, so I'm now giving
it options to scale the output bitmap.
```
options.inSampleSize = 2;
options.inDensity = 2;
options.inTargetDensity = 2;
options.inScaled = true;
```
Android is doing some math between inDensity and inTargetDensity. I don't know exactly what it's doing,
but 2 / 2 looks like it consistently scales the image in half. I've left in my code to to a second scaling pass
of the bitmap in case this doesn't work.

Add some more info to help, remove default zoomable image
