Lots of bad TAB eliminations.
...
I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.
If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces. For example, to see
per-line authors, use "git blame -w <file>". Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".

Switch from except' (from
racket/unit') to #:except' in
2htdp/private'.
...
This is used by the `function-with-arity' macro, and the use of `except'
looks like something that is better done with a keyword. I think that
this change should be fine since it's a private function.

racket' ->

...
All of these look safe. Also, see comment in `2htdp/batch-io' about the
splitting thing (which should probably be revised with the extensions to
`racket/string').

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.

normalize the internal representation of bitmaps so it always uses an alpha
bitmap instead of sometimes using a mask bitmap and sometimes using alpha.
This also fixes a bug where the library would get consfused when it saved
a bitmap to a file, since it didn't record if it was an alpha bitmap or not.
This improves the save files that contain images, cutting the size for bitmaps
in half (bringing the drracket save file down to a mere 25x larger than the
png file format for the example I was using...)
