Optimization for page crop

[GoogleCodeExporter]

Hello, I got some optimization idea for page corp in ebookdroid.

As now, in ebookdroid, if a page need to be croped, the step is
1. decode this page
2. calculate the croppedBounds from the result of 1
3. use the calculated croppedBounds to decode this page again

So as we know, for every page, we need to decode twice.

Now I got a optimization idea is that

1. decode this page
2. calculate the croppedBounds 
3. use the CroppedBounds to drawBitmap directly, with setFilterBitmap to be 
true.

We will decrease the decode times for each page.

I tried this. Awful result. I prefer to wait one more second than read blurry 
image.

Have you tried to paint.setFilterBitmap(true)?
