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'.
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).
A common Slideshow pattern is to put a subset of slides in its
own module with a `run-slides' function, and then you'd
(un)comment a `(run-slides)' call at the end of the module to
work on the subset by itself. Now, you can write
`(module+ main (run-slides))' atthe end of the module and not
have to comment it out. Adding `main' support to the `slideshow'
executable makes it more consistent with using `racket' directly.
Checking first for a `slideshow' submodule makes it possible
for `slideshow' and `racket' to do different things, in case
that's useful.
Renamed `convert' to `pict-convert', etc., to avoid confusion
with `file/convert' bindings.
Moved out of `slideshow/pict' to `slideshow/pict-convert', because
most `slideshow/pict' clients do not need it.
The default is that hiniting is enabled, which causes some text
metrics (notably width) to be rounded to integer values, which makes
spacing more consistent. This default is backward-compatible. The
non-default 'unaligned mode refrains from rounding, which makes metric
information scale correctly and improves output for PS/PDF (such as
Redex output).
The `text' function from `slideshow/pict' defaults to
disabling hinting --- which is consistent with its default to combine
text instead of drawing character-by-character -- so slides and Redex
inherit the improvement.
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More usefully, this patch also fixes a few out-of-date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.
