Deprecated AVLTree and OrderedTuple.
...
These two classes were dirty hacks used only for the extraction of
boundary from 2D Euclidean BSP trees. They were not really efficient and
produces some problems as topology was not preserved.
A completely new implementation of boundary extraction has been set up
as of 3.4, that preserves more topological information and therefore
should be more robust. This new implementation does not use these
classes anymore.
As AVLTree is not really a math concept, this class is not considered to
belong to [math] scope. OrderedTuple is more a grey zone, but it is
really something inefficient and no need for it is foreseen.

Improved accuracy of internal computation.
...
The improvement is obtained by using high accuracy linear combinations
and by preserving cos/sin as much as possible. This last part is
important in the frequent case of lines along y axis, i.e. when angle is
π/2. We want the cosine to remain 0 and not get about 10^-17.

The fact the arrays are reused is stated more clearly, as weel as the
fact changing the time changes the array content.
Yes, it is a bad design, we should change it in the next major version
to allocate fresh new arrays :-(
