Tor Lillqvist f6b4585c98 Build Wintab support always on Windows. Don't require the Wintab SDK. 
2007-01-19  Tor Lillqvist  <tml@novell.com>

	Build Wintab support always on Windows. Don't require the Wintab
	SDK.

	* configure.in: Drop the --with-wintab option. Drop the
	HAVE_WINTAB feature test macro and Automake variable.

	* acconfig.h
	* config.h.win32.in: Drop HAVE_WINTAB.

	* gdk/win32/gdkevents-win32.c 
	* gdk/win32/gdkinput.c 
	* gdk/win32/gdkinput-win32.h 	
	* gdk/win32/gdkinput-win32.c
	* gdk/win32/gdkmain-win32.c: Make HAVE_WINTAB ifdef blocks
	unconditional.

	* gdk/win32/gdkinput-win32.c (_gdk_input_wintab_init_check): Try
	to load wintab32.dll dynamically here. If it is found look up the
	handful Wintab functions we use.
	(rest of file): Use these function pointers instead of calling the
	functions from wntab32x.lib. The code in wntab32x.lib did the same
	thing anyway: tried to load wintab32.dll, and looked up the
	addresses of the actual functions from it.

	* gdk/Makefile.am
	* gdk/win32/Makefile.am: Drop the libwntab32x hacks.

	* gdk/win32/wintab.h
	* gdk/win32/pktdef.h: New files. Copied from the Wintab
	SDK. Copyright blurb says: "The text and information contained in
	this file may be freely used, copied, or distributed without
	compensation or licensing restrictions."

	* README.win32: Update a bit. Remove the text about the Wintab
	SDK.

How to use pktdef.h:
1. Include wintab.h
2. if using just one packet format:
a. Define PACKETDATA and PACKETMODE as or'ed combinations of WTPKT bits
(use the PK_* identifiers).
b. Include pktdef.h.
c. The generated structure typedef will be called PACKET. Use PACKETDATA
and PACKETMODE to fill in the LOGCONTEXT structure.
3. If using multiple packet formats, for each one:
a. Define PACKETNAME. Its text value will be a prefix for this packet's
parameters and names.
b. Define <PACKETNAME>PACKETDATA and <PACKETNAME>PACKETMODE similar to
2.a. above.
c. Include pktdef.h.
d. The generated structure typedef will be called
<PACKETNAME>PACKET. Compare with 2.c. above and example #2 below.
4. If using extension packet data, do the following additional steps
for each extension:
a. Before including pktdef.h, define <PACKETNAME>PACKET<EXTENSION>
as either PKEXT_ABSOLUTE or PKEXT_RELATIVE.
b. The generated structure typedef will contain a field for the
extension data.
c. Scan the WTI_EXTENSION categories to find the extension's
packet mask bit.
d. OR the packet mask bit with <PACKETNAME>PACKETDATA and use the
result in the lcPktData field of the LOGCONTEXT structure.
e. If <PACKETNAME>PACKET<EXTENSION> was PKEXT_RELATIVE, OR the
packet mask bit with <PACKETNAME>PACKETMODE and use the result
in the lcPktMode field of the LOGCONTEXT structure.
Example #1. -- single packet format
#include <wintab.h>
#define PACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/
#define PACKETMODE PK_BUTTONS /@ buttons relative mode @/
#include <pktdef.h>
...
lc.lcPktData = PACKETDATA;
lc.lcPktMode = PACKETMODE;
Example #2. -- multiple formats
#include <wintab.h>
#define PACKETNAME MOE
#define MOEPACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/
#define MOEPACKETMODE PK_BUTTONS /@ buttons relative mode @/
#include <pktdef.h>
#define PACKETNAME LARRY
#define LARRYPACKETDATA PK_Y | PK_Z | PK_BUTTONS /@ y, z, buttons @/
#define LARRYPACKETMODE PK_BUTTONS /@ buttons relative mode @/
#include <pktdef.h>
#define PACKETNAME CURLY
#define CURLYPACKETDATA PK_X | PK_Z | PK_BUTTONS /@ x, z, buttons @/
#define CURLYPACKETMODE PK_BUTTONS /@ buttons relative mode @/
#include <pktdef.h>
...
lcMOE.lcPktData = MOEPACKETDATA;
lcMOE.lcPktMode = MOEPACKETMODE;
...
lcLARRY.lcPktData = LARRYPACKETDATA;
lcLARRY.lcPktMode = LARRYPACKETMODE;
...
lcCURLY.lcPktData = CURLYPACKETDATA;
lcCURLY.lcPktMode = CURLYPACKETMODE;
Example #3. -- extension packet data "XFOO".
#include <wintab.h>
#define PACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/
#define PACKETMODE PK_BUTTONS /@ buttons relative mode @/
#define PACKETXFOO PKEXT_ABSOLUTE /@ XFOO absolute mode @/
#include <pktdef.h>
