Scrolling performance

OK, I guess it's time to start talking about the v2.0 update. Among the new functionality (more on that later), I fix a minor scrolling performance problem that happens under the following scenario:

• Select book
• Select chapter 1
• Scroll right to chapter 2
• Scroll right to chapter 3
• Notice that scrolling in chapter 3 is not smooth

The same thing happens if you select the last chapter of a book and then scroll left two times. The fun thing is that from then on, as you scroll through the chapters, every third chapter will have unsmooth scrolling. I'll leave it as an exercise to the reader to figure out why. ;)
