2htdp/image
...
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...)

"under <platform>" -> "on <platform>"; "X" -> "Unix"
...
I originally picked "under" as the preposition to go before
a platform name, but obviously you should build "on" a
platform, and "under" suddenly annoys me. The choice of "on"
is now codified in the documentation style guide. Meanwhile,
"Unix" insted of "X" seems more clear and consistent in the
`racket/gui' docs.
More usefully, this patch also fixes a few out-of-date
platform-specific claims.

Two improvements to the mrlib/graph library and the module browser:
...
- improved the drawing speed in mrlib's graph pasteboard
by caching the background arrows (optionally; only turned
on for the module browser. in redex, this probably won't
speed anything up so it isn't used)
- added a search feature to the module graph to help find
dependencies; type in string and some of the graph changes
