Comment(by idefix):
Well, it look likes the
[http://linuxwacom.cvs.sourceforge.net/viewvc/linuxwacom/linuxwacom-
dev/src/2.6.30/wacom_wac.c?view=markup#l_690 "Linux driver"] uses a
different method for the Intuos3 and Cintiq to calculate the absolute
coordinates:
{{{
#!c
input_report_abs(input, ABS_X, (data[2] << 9) | (data[3] << 1) | ((data[9]
>> 1) & 1));
input_report_abs(input, ABS_Y, (data[4] << 9) | (data[5] << 1) | (data[9]
& 1));
}}}
While Haiku [source:haiku/trunk/src/add-
ons/input_server/devices/wacom/TabletDevice.cpp#L298 uses]:
{{{
#!cpp
xPos = data[2] << 8 | data[3];
yPos = data[4] << 8 | data[5];
}}}
Which would explain the halving of the position in Haiku.
