**Task:** Pass ''tests.BoundsConstant''.

A first, very crude approximation of the bounding box, would be to return the entire drawing canvas. This is certainly very fast to calculate (it is a constant value), although it might mean excessive redrawing.

Implement an aspect to return the entire canves when the ''getBounds()'' method of a ''Group'' is invoked. The entire canvas can be retrieved through the static field ''MAX_BOUNDS'' of ''FigureElement''.

<note tip>
You can override the ''getBounds()'' method entirely with ''around'' advice intercepting the method.
</note>

This should make the test cases of ''tests.BoundsConstant'' pass.

When done, remove the aspect from your build path. Continue with [[caching:ex2|Exercise 2]].
