These are small but they do show up in sp3 profiles.

IsPaintingToWindow is always true, so just assert it.

HaveScrollableDisplayPort is a simple pointer check, whereas AsyncPanZoomEnabled needs to jump several pointers (and WantAsyncScroll is slower yet), so change the order.

HasNonMinimalNonZeroDisplayPort is not needed unless we are inside that if, so don't call it outside the if.
