TYPE: CHOP
TITLE: Mouse CHOP

This CHOP outputs X and Y screen values for the mouse device.

The Mouse X and Y positions are output through the channels named in the
Position X and Y parameters, when the Active flag is on.

The mouse ranges are -1 to +1 in X, approximately -.8 to +.8 in Y.
They are scaled by the larger of the horizontal resolution and
vertical resolution of the screen, so the exact Y range can vary.
0, 0 is the center of the screen.

The Mouse and Keyboard CHOPs are often connected to the Position and Active
inputs respectively of the Record CHOP to enable the recording of channels.

The Use Tablet option allows the sampling of the current state of the
active tool on a tablet.  If no tools are on the tablet, the values
are undefined.

The Channel tab lets you set the Sample Rate and the Extend Conditions.

There are no local variables.

Parameters:
