Description
Adds the ITransformProvider2 pattern that allows UI Automation / Accessibility tooling to zoom.
TODO: Use the Microsoft UI Automation Component Object Model (COM) interfaces instead to call the new TransformPattern2 methods in
uiautomationcoreapi.h, since the new APIs doesn't support the old p-invoke methods which are deprecated.wpf/src/Microsoft.DotNet.Wpf/src/UIAutomation/UIAutomationClient/MS/Internal/Automation/UiaCoreApi.cs
