sqInt ioSetCursorWithMask(sqInt cursorBitsIndex, sqInt cursorMaskIndex, sqInt offsetX, sqInt offsetY)


Parms:
cursorBitsIndex pointer to oops, data bits describing cursor
cursorMaskIndex pointer to oops, data bits describing mask
offsetX integer, offset to hot spot X, the pixel where the click is
offsetY integer, offset to hot spot Y, the pixel where the click is

return: NONE, fake return of zero
From: Interpreter
Why:
To set the host system cursor and host spot

Responsibility:
Also see ioSetCursorARGB which is bigger cursor support
On the macintosh we have logic to set/reset the cursor depending on if the cursor is inside or outside of the drawing surface. Some platforms may do this automatically, others require support in the VM to enable this feature.

MacIntosh
os-9/OSXCarbon
If headless or not drawing in the browser yet then return
Set bigger cursors to off
Copy the data from the Squeak oops into a MacCursor, respect issues with powerpc/intel
Check to see if we need to send the cursor to the browser plugin, or we have to draw it because we are full screen in the browser, or running
not as a browser subtask. Then use OS-9 era call to set the cursor.

Cocoa:
Grind thru the data to use NSCursor to set the cursor.

iPhone
The iPhone has no concept of a cursor, so the api does return 0

Unix
Use X-Windows to display the cursor in the proper endian

Windows
Use create and set cursor, return 1

BUGS

Platforms return 1 or 0 which are cheerfully ignored.
