>= 33s

... and even longer times for other line types.

I tried this code on my tiny little Libretto (Pentium 120Mhz, 32Mb
ram, 20gb drive) running Win95, and it was noticeably slower doing the
line types other than type 1, but not nearly as slow as described.
I'd suggest you're short of some sort of graphics resource, or there's
a Win2K bug here.
