# This patch is from http://www.postnuklear.de/xorg-patches/
#
# Description: This is a patch for the evtouch input driver (
#              http://stz-softwaretechnik.com/~ke/touchscreen/evtouch.html).
# Changes (for full description see ChangeLog file after patching (-: ):
#   o Changed code to compile a working driver for both XInput ABI 0.x and 2.0 (Xorg 1.4.0)
#   o changed rotation (due to segfault on xorg + fbdev)
#   o drag support
#   o tap "tolerance"
#   o added generic ts-adc touchscreen device to udev rules file
#
# Feel free to send comments, critics, suggestions to harryrat@postnuklear.de
# To apply simply change into the toplevel directory of the source to be modified and enter:
# patch -p1 < <PATH_TO_PATCH>

+0.8.7-HR *** Note this is not an official release but an "unauthorized
+	 *** fix version by me (Harald Radke - harryrat@postnuklear.de)
+	-> Changed code to compile a working driver for  both 
+	  XInput ABI 0.x and 2.0 (Xorg 1.4.0)
+	  (test compile for 0.x still needs to be done)
+	  - evtouch.c: 
+            * capsulated xf86Post*Events and xf86InputSetScreen 
+	      in functions where depending on the XINPUT ABI conversion
+	      is done or xf86 functions are directly called
+	    * xf86InitValuatorAxisStruct and xf86AlwaysCore() depending
+	      on ABI done
+	  - libtouch.h: passing xf86PostButtonEvent capsulation function
+	    to init function (same as in evtouch.c) to do proper button
+	    triggering
+	-> Rotation:
+	  - added support for Option "Rotate" "UD" (upside down) 
+	     in evtouch input section of xorg.conf
+	  - due to Segfault with (at least) fbdev video device, only
+	    evtouch "Rotate" option is taken into calculations for coords,
+	    meaning to get proper touchscreen behaviour on rotated X screens.
+	    same Rotate option as in video device section of xorg.conf has
+            to be set in the evtouch section
+	-> Drag support:
+	  Option "<STATE>_drag" "<BUTTON_ID>" has been added. When set,
+	  the handle_<STATE>() function triggers BUTTON_DOWN for Button <BUTTON_ID>
+	  before changing into S_MOVE state. Note that actually only
+	  Option "touched_drag" "<BUTTON_ID>" is implemented, rest is dummy
+	  (and doesn't make too much sense I guess) (-;
+	-> tap "tolerance":
+	   introduce move_limit to evtouch.c as it is in libtouch.c, using it
+	   to discard ABS_X/Y position changes if they are inside move_limit
+	   around cur_x/y. this way pointer hopping can be avoided as well as
+           proper touched_drag established
+         - changes of cur_x/y are reported on EV_SYN in evtouch.c ReadInput() instead
+           on EV_ABS
+	-> added generic ts-adc touchscreen device to udev rules file	   
+
+	=>  Example for a Loox720 PDA setup in input section of xorg.conf:
+		Section "InputDevice"
+		 Identifier "touchscreen"
+		 Driver "evtouch"
+		 Option "Device" "/dev/input/evtouch_event"
+		 Option "MinX" "434"
+		 Option "MinY" "333"
+		 Option "MaxX" "3643"
+		 Option "MaxY" "3804"
+		 Option "SwapX" "true"
+		 Option "longtouched_action" "down"
+		 Option "longtouched_button" "3"
+		 Option "maybetapped_action" "click"
+		 Option "maybetapped_button" "1"
+		 Option "touched_drag" "1"
+		 Option "oneandahalftap_button" "0"
+		 Option "TapTimer" "30"
+		 Option "LongtouchTimer"  "500"
+		 Option "MoveLimit"  "18"
+		EndSection
