* generic/tkScale.c: header file. All tk*Port.h files have long
had a #include <math.h>, and other parts of Tk routinely make use
of libm-supplied math routines.

updating Tk to use Tcl 8.4's fully CONST-ified
interface, and fully CONSTifying Tk at the
same time.
This patch includes purging Tk of its last
direct access to interp->result. [Bug 589853]
The substantial changes include copying
event sequence strings into Tcl_DStrings
in tkBind.c, and copying [text] indices into
Tcl_DStrings because parsing them involved
overwriting them. If this causes performance
trouble, that can be resolved by further
converting them to Tcl_Obj's.
The #defines USE_NON_CONST and USE_COMPAT_CONST
have the same effect for Tk as they do for Tcl.
(They actually change tcl.h)

TkClassProcs/TkSetClassProcs as Tk_ClassProcs/Tk_SetClassProcs,
adding a size field to Tk_ClassProcs to allow for future
expansion, and renaming the geometryProc to worldChangedProc,
which is more in keeping with the actual use of the callback.
See ChangeLog for details.
