mtdev

Plugin Name: mtdev (-omtdev,...) / Shared Library: libgre-plugin-mtdev
bounds=[X1:Y1:X2:Y2]	Where X1,Y1 is the top-left corner and X2,Y2 is the bottom-right corner of the touch screen device. On some screens, X1 may be less than X2 and Y1 may be less than Y2.
calibrate	Puts mtdev into raw mode to be used in conjunction with the mtcalib application (See Crank Public SVN) to acquire the bounds parameters for screen calibration. Use the -omtdev,bounds option to pass the parameters to sbengine.
device=[path to touch device]	Plugin for Linux Multi-Touch Protocol to be used with kernels supporting multi-touch events.
points=[integer]	This is the number of multitouch fingers that is supported. Events will only be generated for this number of fingers in contact with the screen, the default is 5.
rotate=[0|90|180|270]	Clockwise rotation of the touch input coordinates. This option is not often required. By default, mtdev plugin input will be rotated depending on the render manager configuration. The input transformation will be calculated by combining the specified rotation value and the render manager rotation.
threshold=[integer]	This is the number of pixels a touch point has to move in order to generate a motion event, the default value is 1.
