    bitmask: Fix intersection code
    
    With the fix in 77912a65e2aa6eb9cfee994fa93bbfbc6b9f8538, another bug
    got visible: booleans are 32 bits, so if the intersection between the 2
    bitmasks happened in higher bits, the return value would be truncated to
    FALSE.
    
    This actually made slider handles disappear, so it was pretty visible.
