Determines if Sculptor is using a Windows theme or a classic style (sys.UseTheme)

sys.UseTheme,,u1

Indicates if a Windows theme is being used

This variable returns zero if Sculptor is using a classic style, or a non-zero value to indicate that it is using a Windows theme.

On versions of Windows that support themes, sys.UseTheme can be changed at run time.

The !compat notheme declaration can be used to force the classic style.
