I haven't looked, but based on what you're saying I would assume that each
Frame just tracks its own data, and none (including the parent) has knowledge
of what's in the others.

There might already be a method for this that I don't know about.  If MCMLXXIX
is around, he might have some comments.  For now I'll suggest:

I think that we can probably add a method that will return a flattened version
of each frame's .data array, with the topmost layers taking precedence over
data from those below.  Here's something that you can try:

- Get your layers of frames set up as you've described
- Call .screenshot(system.text_dir + "blah.bin", false) on the parent frame
- Open text/blah.bin in an ANSI editor; column width is same as frame width was

If blah.bin has the image that you're expecting (all of the contents of the
frames tht were visible at the time), then that's a good start and we can move
on from there.  I'll make a Frame.dump method that will do what you're looking
for.

If not ... something else can be done.
