I expect this method to tell me the size of a rectangle (e.g. a bitmap context)
such that if I draw my attributed string into that rectangle, it will all fit.
When I say "all" I mean "all", including the margins.
Instead, this method is telling me the size of a tight rectangle around the
black marks the letters make. That is not at all the same thing.
It is easy to see the difference. Let's say I say this:
CGRect r = [as boundingRectWithSize:CGSizeMake(100,10000)
options:NSStringDrawingUsesLineFragmentOrigin context:nil];
And let's say the answer is {51.8027, 465}. Well, if I try to draw my string
into a rect of size {51.8027, 465}, it won't fit. That's because the 20pt
margins will be applied within those bounds, so my text will be trying to fit
in an 11pt space, and will be much longer than 465pt high.
Therefore I believe this is a bug. I asked for the bounding rect of my string,
but the system gave me the bounding rect of a *different* string, a string that
has no margins. m.
