    pthreads now work
    cleaned up mac.c (from original OSXvnc); now compiles (untested!)
    compiles cleanly on Linux, IRIX, BSD, Apple
+   fixed prototypes

    rewrote API to use pseudo-methods instead of required functions.
    lots of clean up.

        doing a CopyArea from a pixmap to the screen, where the pixmap contains
        the saved contents of the screen under the cursor.  Before doing this,
        however, we set cursorIsDrawn to FALSE.  Then, when CopyArea is called,
        it sees that cursorIsDrawn is FALSE and so doesn't feel the need to

        that PushPixels doesn't think it has to remove the cursor first.
        Obviously cursorIsDrawn is set to TRUE afterwards.
