The new keys are useful for skipping animation groups. They
actually navigate by slide name, which defaults to the slide title,
but can be specified separately with the `#:name' argument to
`slide'.
Separate parameters for props to serialize and those to transfer.
Make syntax?/list? checks on attributes explicit.
Also add continuation barrier around metafunction application.
Instead of `shift' and `reset'. Performance is a little better,
since `call/cc' acts as hint to the run-time system that the
continuation doesn't need to compose.
message at the end of the transcript and so that it shuts down
the installation custodian (which means that any threads or
anything like that that the .plt file's code may have created
will die, plus that the "abort installation" button will now
be greyed out)

This instructs the adventurer on how to take screen shots using the
same look and feel used to take the ones that can be found at
`collects/scribblings/gui/image'.
There are also two scripts that might help automate this process.
It's very helpful to have a visual aid when dealing with a graphical
interface toolkit.
This patch adds an overview of the widgets available in the library
consisting of screen shots of the main ones and the snippets used to
produce them.
Each widget image link back to the full documentation.
The `slideshow/code-pict' library is the same as `slideshow/code', but
it works in non-GUI settings. Only the `slideshow/code' library connects
the code font size to `current-font-size', though.
The `code' macro, `define-code', etc., now support "code transformers",
which are syntax bindings that trigger otherwise-unescaped transformations
in the code to typeset (which can make the code easier to read and
friendlier to auto-indentation).
Other major changes:
- pg code now uses only binary format
- pg timestamptz now always UTC (tz = 0), added doc section
- added contracts to most pg "can't-convert" errors
choose to print to pdf as well. Also, enable the preference
under linux (ie, make it available to be chosen-- all platforms
still default to printing via the platform-specific mechanism)
Support for break clauses complicates expansion to `for/fold/derived';
a new `syntax/for-body' library provides a helper for macros that need
to split a `for'-style body into a prefix part and wrappable part.
Allows the use of `in-generator' to produce multiple values in a
position other than immediately within `for' (where the arity
can be inferred).
