Microsoft did at some point extend the roles in MSAA with two extra
roles (ROLE_SYSTEM_IPADDRESS and ROLE_SYSTEM_OUTLINEBUTTON).
These are defined in oleacc.h as:
#define ROLE_SYSTEM_IPADDRESS ( 0x3f )
#define ROLE_SYSTEM_OUTLINEBUTTON ( 0x40 )
This means that LayeredPane will map to ROLE_SYSTEM_IPADDRESS
and Terminal will map to ROLE_SYSTEM_OUTLINEBUTTON, which is
obviously wrong.
We now reserve some valuespace for more roles to reduce the likelyness of
any collisions in the future. Having the reserved area also serves
as a way of indicating the boundary between the "MSAA" enums and other
enums.
