These additions could create backward-compatibility problems, but our
searches suggest that problems will be rare; it's more common for
`_size_t' to be incorrectly aliased to `_int', so having definitions
for these standard types is likely to avoid future problems.
commit e503850f21 broke drracket's
interactivity (for some files it could take 2 seconds to do
that one line)
This changes the bindings-table so that it maps to sets instead of
lists. Now, instead of mutating all entries in the table right after
collecting everything, just leave them as sets until we need the info
and just sort a single entry, when it is needed
The check was incomplete in the case that both arguments to a binary
[ext]flonum function need to be checked and the second one was not an
[ext]flonum and also not a fixnum.
The problem was exposed by improved error checking
in the expander to detect references to exports of a module that
is not yet visited, and as triggered by the documentation for
`2htdp/planetcute'.
A part with style property 'toc-hidden no longer
hides child sections, which makes it consistent with Latex/PDF
rendering.
A part with style 'grouper and 'unnumbered does not make its
child parts render as more nested, which is consistent with
'gruper without 'unnumbered. An unnumbered grouper is represented
as "" in a section-number list (while #f is still used for
unnumbered non-grouper layers).
Includes a repair for floating-point `min' and `max' that affects all
x86 builds that use SSE arithmetic, leaving the (otherwise unused)
floating-point stack in a bad state, which might have affected
x87-using C/foreign libraries running alongside Racket.

specifically, if the before and after green line are right
next to each other, then put it into a single edit sequence
(which unions the invalidated regions); if not, then we
may be jumping far away, so invalidate the two regions
and redraw them separately
