Hello,

I think that the underlying principle "Everything is an expression" in
Mathematica is great and is one of the most exciting advantages of the
Mathematica system.

But it is disappointing that this principle is still fails even on
such basic example as representation of a simple Plot. Consider the
following:

g = Plot[Sin[x], {x, 0.2, 10}]
Show[FullGraphics[g], AspectRatio -> 1/GoldenRatio]

It is clear that the two generated images are significantly different.
This means that the function FullGraphics[] does not gives the true
expression-representation of the first plot. Is it true that in really
we can not get the true representation of the plot as an expression?
And the principle mentioned really fails even on this? Or there is
another way to get it?

Thank you for your attention a priori.
