68e005fb2c racket/draw: make-immutable-{color,brush,pen} => make-{color,brush,pen}
Also, use keywords for `make-pen' and `make-brush'.

Adding `make-pen' and `make-color' creates many conflicts among
teaching libraries, such as `2htdp/image'. These are easy to fix
up in the tree, but adding such obvious names to `racket/draw'
may create other compatibility problems, so we might have to reconsider
the names.

In consultation with Asumu.

8db45eb557 Add immutable constructors for color%, brush%, pen%
- Make set-immutable a local method and document
    is-immutable? as a public method
  - Add some racket/draw tests

4f197f4ba9 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.

ac26fe7554 A ton of @scheme*' -> @racket*' and related updates.
Also, updates some of the mzlib files to point at `racket/*' libraries
rather than to `scheme/*' ones.

(Some other minor things here and there.)
