racket/draw: add get-handle' to bitmap%'; add `make-handle-brush'
...
The `get-handle' method provides the underlying Cairo surface for
a bitmap, while the unsafe `make-handle-brush' function supports the
use of a Cairo surface as a `brush%'.
Also, add `racket/draw/unsafe/cairo-lib', which simplifies access
Cairo from external libraries. Documenting `racket/draw/unsafe/cairo'
might be better, but that's a lot more work.

fix region% problems
...
- fail gracefully with pre 1.4 Cairo
- clip all drawing for an empty clipping region
- disallow `is-empty?' on a region without a DC
(since the test depends on the DC dimensions)
