Chapter 5 Notes (staqrt on Fitting text to available size)
Title: Dealing with Sizes
Summary
This chapter covers the consequences of different sized pixels and how we treat them.
Oh that screen drivers were built report screen size and to take unchanging units like inches and translate them based on the hardware. This would be a non-issue as we would always specify things in inches. BUT of course we would be discussing the exponential scaling curve that dictates how much you can scale down... (think dpi as a scaling factor). Then the curve might be <<latex($ScaleFactor = B e^{-x}$)>>
