Things should now generally be set up to work better --
for example online check syntax is smarter now about
what happens when switching tabs/frames and this also
makes it easier to add new ways for a window to become
dirty (that is, for it to be known that it needs to
be recompiled)
Keep track of whether any Racket-managed subprocesses are pending,
and use waitpid(0, ...) only if there is one, to better cooperate
with an embedding environment.
Also, add a chapter to the "Inside" manual to explain the issues.
* `list->array' now accepts an optional shape argument, and always returns
an immutable array
* `vector->array' now accepts an optional shape argument, and always
returns a mutable array
* Removed `make-mutable-array' because `vector->array' does its job now (I
never liked the name anyway)
* Renamed `unsafe-mutable-array' to `unsafe-vector->array'
* Added optional type annotation to `array' macro to match `mutable-array'
* Reworded error messages in array broadcasting functions
* Made minor array doc fixes
Also allow `#:break' and `#:final' in all the `for:' macros.
Unfortunately, the expansion of `#:break' and `#:final' cannot be
typechecked at the moment.
renamed `partition-count' to `partitions' to be consistent with
`permutations', and gave better examples in `multinomial' docs
* (flulp-error +inf.0 +nan.0) was returning +nan.0 instead of +inf.0
* Type of `multinomial' didn't match its docs or `flmultinomial'
* Reworded docs for `diagonal-array'
* Reworked/reordered quite a few things in docs for `math/bigfloat'
* Fixed first identity given in `gamma-inc' docs
* Fixed descrption for `+max.0', etc.
Changing `current-url-encode-mode' from 'recommended to 'unreserved
causes `url->string' to encode !, *, ', (, and ) using %, which
can avoid confusing some parsers.

Presumably, values shouldn't ever wrap and the bytestring is already
assured to be long enough, so using safe operations isn't strictly
necessary. This dangerous improvement yields speedup factor of ~1.86.
In set-argb-pixels, the critical loop for each pixel tests the value
of a boolean that was defined at the top level of the class. Forcing
these to be local variables gives a speedup of 1.5.
As long as some thread is ready to run, and in case the threads
synchronize after very little work, keep checking threads for
at least one thread quantum.
I also made some minor changes to `plot' so that its functions would
type more easily. In particular, everything that used to take a list
of vectors now accepts a (Sequenceof (Sequenceof Real)). The 3D
discrete histogram renderers now also accept lists as well as vectors
in the sequence of categories.
For now, in typed/plot functions, optional non-keyword arguments are
required. As soon as Vincent closes PR 13354, I should be able to
uncomment part of a macro in "typed/plot/syntax.rkt" to make them
correctly optional.
