Grabbing the mouse

Is there a way in squeak to completely grab the mouse so you can
get all events, and not even bother with the cursor? a lot of
games do it for various features, and trying to do the same in
Open Cobalt for the camera controls

No. I think we used platform-specific FFI calls for that, but can't remember the details.

I discovered that there is InputSensor >> cursorPoint: that
claims to move the mouse pointer position, but the primitive
seems to be un-implemented on all three platforms.

To try it:

Sensor cursorPoint: 100@100

It uses primitive 91, but that doesn't change the cursor position anymore:
(91 primitiveTestDisplayDepth) "Blue Book: primitiveCursorLocPut"

You can do it with FFI calls. On windows it's:

setCursorPosX: x y: y

<apicall: bool 'SetCursorPos' (long long) module: 'user32.dll'>
^self externalCallFailed

Note that x and y are absolute values, not relative to the current window.
