Is it just me or is it weird that I can change a view's unit square, that
it remembers the cumulative changes, and yet I can't ask it what the
current variation is? I'm keeping track already, but now I realize I
wouldn't have to if I could query this myself. I suppose this is contained
within the draw matrix somehow, but I don't feel good trying to hack it.
But I just wanted to know if I was missing anything.
Why am I changing the unit square at all? So that the rulers on my scroll
view look right. (I'm doing everything else myself because I'm using
OpenGL.) Which suggests the question, how do the rulers know the relative
scale of my content view? These aren't critical questions but I'm very
curious.
