672910f27b 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>".

7d6e79023c Random pickiness. 
Spaces at EOFs, indentation, etc.

c7666c5e4f In addition to providing "provide", I also provide several of its 
sub-forms, most usefully "all-defined-out".

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.

c769481d9d Previous commit mistakenly exposed a debugging function "show-cache". 
It is no longer exported.

656713cbcf Enlarged cache for get-pixel-color from one image to 3, so you can 
alternate among three images without thrashing and re-rendering.

ba8684cb63 provide provide, so it's possible to use provide and require in 
student languages.  This will be a problem if somebody writes a
function in BSL or BSLLA, provides it, requires it in a non-student
language, and uses it as an argument to a higher-order function
that isn't declared as a "higher order primitive".  That is,
not very often.  Even if so, just re-open the BSL or BSLLA source
file, switch languages to ISL, save it, and the problem goes away.

39629e8e99 map-image and map-image/extra now give their function argument x and y 
coordinates, or not, depending on the arity of that function.  This
enables one to write a simple function from color -> color and
immediately map it on an image.  For the situation in which the
function is location-dependent, one can still write a function from
x,y,color -> color and map this on the image.

d61eb53686 Lots of documentation formatting. 
Started as fixing misindented definitions, then more indentations, then
a bunch of similar things (square brackets, huge spaces at end-of-lines,
etc).

type.  Still produces one check-error failure because of bug in
make-color.

40124a0619 A long overdue scan to eliminate files without terminating newlines. 
(DrRacket should really do that.)

rather than to `scheme/*' ones.
