The way I understand it is that "save bits behind" should be thought of an
optimization and not counted on. Just so happens it works most of the time,
and if your app is very conservative with memory it will work all the time.
My only complaint is that it maybe forces me to make my app a tiny bit
bigger to deal with a condition (not enough mem) that probably never will
happen. On the other hand this is more likely with color, and my app has to
be able to paint most of the screen anyway so it's just a matter of better
code organization.
