Fix RSS exploding when zoom in on large pages #122

Might also worth considering that we crop the scaled image to cover only the visible rect... Any thoughts? Would that break too many parts?

Now it takes about 120mb for a 3000*4000 page to scale up to 2.0, it won't work well if we scale it all the way up to the max scale of 7 or higher

@espresso3389 closed the pr since I saw your changes, but the question remains.. Still value your thoughts when you get a chance to look at it. And I notice a few blink(no pdf image showing up for a ms) when move/scale using the latest 1.0.52. I'm looking at it, but if you already know/fix the issue, please let me know :)

Yes, I also realized there are blinks on certain operation. I'm checking it.
