This presumably wants to be Size(-1, -1)

The code had been introduced with bd837fcbae7662bd127cb214f1497e4bf750cab0
"#92085# GetRulerState(): setting of SID_RULER_LR_MIN_MAX corrected" (where the
referenced bug is apparently from the lost Sun-internal bug tracker), at a time
when Size was presumably based on signed long, so ULONG_MAX presumably already
effectively meant -1 back then.

I don't understand what this code does, but when using a

  Size(std::numeric_limits<::tools::Long>::max(),
       std::numeric_limits<::tools::Long>::max())

instead, in a 64-bit Linux UBSan build I got

when creating a rectangle in Draw and clicking around in it.  Whereas with

  Size(-1, -1)

things appear to work fine.
