Clipping for RECT types. Breaks a little.
When using QuadTrees, RECT_OUTLINE and RECT_FILLED are clipped to

This lets you zoom in forever on rectangles with a couple of caveats:
1. This is technically wrong for RECT_OUTLINE, as more lines will be added.
2. There are a couple of issues related to the fact that only one node is
visible at a time. Notably:
(a) You lose the infinite precision when stradling a quadtree boundary,
which will happen eventually.
(b) Zooming out will show random broken things.

both the RECT and the BEZIER are in view, the RECT moves smoothly and the BEZIER

There are some issues with the boundaries of quadtree nodes, as the system

tree until it finds a single node which contains both, though this will be
a distant anscestor if the nodes are distantly related.

Change Rational<Arbint> -> Rational<Gmpint>
Works better (not surprising). Can change back @real.h:52

Now with GNU MultiPrecision (GMP) integers
gmpint.h is (in theory) mostly inline and shouldn't add much overhead
and was simpler than trying to understand the C++ "binding".
The Str() function is kind of terrible but that can't be helped.
Also fixed bug in realops tester (even the testers have bugs...)
And removed asm tester because the asm function is gone.
The bezier testers now don't compile, I don't think we need them anymore.
