Treat a "face" as a font description only if it has a comma,
otherwise go back to treating it as a family name.
This change fixes the problem of parsing "Times New Roman"
as "Times New, Roman".
Extend `define-cstruct' to support #:property specs, which causes
the constructor and C->Racket coercsions to wrap the pointer in
a structure instance with the specified properties. Of course,
the wrapper structure has a `prop:cpointer' property so that the
wrapper can be used transparently as a C pointer.
Add missing tests and documentation for the id`->list', `list->'id,
id`->list*', and `list*->'id bindings created by `define-cstruct'.
This addition triggered several other changes:
* -k for a Mac OS X embedding is now relative to the __PLTSCHEME
segment (which means that executables won't break if you strip
them, for example)
* the command-line no longer has a limited size for Mac OS X
launchers and embedding executables
* Mac OS X GUI and Windows launchers record the creation-time
collection path, unless they are created as "relative" launchers
In particular, allow a pair of a relative-to directory and a base
directory. Paths that syntactically extend the base directory are
recorded as relative to the relative-to directory (which must
syntactically extend the base directory).
The compilation manager now sets the parameter to a pair with
the base directory as the main collection directory, if the source
file's path extends that directory's path.
This generalization solves problems created by cross-module inlining,
where the source location of a procedure in bytecode can now be in a
different file than the enclosing module's file.
Also add a test that checks whether the build directory shows up
in any ".zo", ".dep", or documentation ".html" files.
Closes PR 12549
Setting the environment variable causes the bytecode compiler to run
the bytecode validator (which is normally applied to input from a
bytecode file) immediately on all of the compiler's own results.
