be NULL.
* generic/tkConfig.c (Tk_RestoreSavedOptions): For custom options,
added test that the restoreProc is not NULL, to allow for custom
options that don't care about supporting Tk_RestoreSavedOptions.

* doc/SetOptions.3:
* generic/tk.h:
* generic/tkConfig.c: Changed interface for Tk_CustomOptionSetProc
and Tk_CustomOptionGetProc; these now take a pointer to the start
of the widget record, and an integer offset to the slot for the
option value, instead of just a pointer to the slot. This allows
more sophisticated options to do interesting things based on other
data in the widget record.

used for TK_OPTION_CUSTOM, and typedef's of the functions
Tk_CustomOptionSetProc, Tk_CustomOptionGetProc,
Tk_CustomOptionRestoreProc, and Tk_CustomOptionFreeProc, used for
TK_OPTION_CUSTOM.
* doc/SetOptions.3: Added documentation of TK_OPTION_CUSTOM, and
section "CUSTOM OPTION TYPES" explaining how to create and use
custom options.
* tests/config.test: Added tests for custom option type.
* generic/tkTest.c: Added test support for TK_OPTION_CUSTOM to
TestobjconfigObjCmd. Added CustomOption* functions to implement a
test custom option.
* generic/tkConfig.c: Added new option type TK_OPTION_CUSTOM,
which allows the definition of custom option types by creating
parsing, printing, freeing, and restoring procedures for a custom
option. This is needed by the text and canvas widgets if they are
to be fully objectified.

TK_OPTION_NULL_OK for TK_OPTION_DOUBLE and TK_OPTION_PIXELS.
* generic/tkConfig.c: Added for TK_OPTION_NULL_OK support for
TK_OPTION_DOUBLE and TK_OPTION_PIXELS.
* doc/place.n: Updated, reformatted manual entry.
* tests/place.test: Added many tests.
* generic/tkPlace.c (Tk_PlaceObjCmd): Updated to use Tk
widget-option management facilities to manage place options (-x,
-y, etc.), which simplifies the placer code. Added support for
[place configure pathName] and [place configure pathName -option],
similar to the behavior of the configure subcommand supported by
widgets.
