* fix a bug in initialization of FrTime widgets
* fix a bug in the pong demo
* allow needles and growing points to have larger grids
* purge the old GUI wrapper implementation
* fix a couple of bugs in the debugger
* add bitmap support to the animation library

- use an editor-snip% to make frtime's value rendering work correctly
(though not as prettily) when several snips are embedded within a data
structure
- fix frtime's choice, radio-box, and list-box widgets
- improve debugger's handling of variables, etc.
- allow HtDP languages to enable the debugger, and do so for Advanced
language
svn: r8780
file. (That is, it does not require the file to have a `name'
entry.)
* The name shown when setup works is the directory name, followed by
the `name' field from the info file when specified.
* This means that many `name's are no longer needed, so I'm removing
them. To see if you need a `name' entry, consider that the name
will be shown like this:
... foo (<your name here>)
This means that if the name is the same as the directory name, then
there is no point in having it. I also removed cases where the name
differed only in its capitalization for collections where the case
is obvious.
* Also, for subcollections, the name should clarify the name of the
subcollection in context. For example "Acknowledgments" explains
what scribbling/acks is, but there's no need to add the context name
as in "Scribblings: Acknowledgments".
* There may also be a point in keeping names for other uses. One such
example was in games, where the name field was used in the PLT Games
application. (This was changed to default on the directory name, so
it is no longer needed in most games.) Another example is in planet
packages.

- improves performance
- allows letrec to build cyclic structures (lists & vectors at least...)
value display in REPL finally respects language preferences, use of snips by underlying renderer (e.g.,
TexPict)
GUI bindings are compiled as separate sub-collection (reduces load time)
svn: r6840
languages other than (module ...)
made push-pull-ball not a module, so it just runs in FrTime
removed velocity display from pong.ss, and moved default location of left
controller so it doesn't cause div-by-zero exceptions
svn: r3718
on machines with networking completely turned off
- added find-listener/port, which may be used in the future to enable
networking explicitly (though erl.ss will need significant mods for that)
- removed mention of distribution in README for demos (i.e., net-pong demo)
- minor bug fix in gui wrapper
- noted that spreadsheet is broken on MacOS
svn: r3403
compiler/garbage collector
- fixed div by zero bug in pong.ss demo
- removed defunct net-pong demos and ft-spread
- added documentation and demo sheet for spreadsheet
