Raise WPF touch events using WM_TOUCH instead of the lag-prone default implementation

WmTouchDevice

WmTouchDevice contains a basic implementation of WPF's TouchDevice class based on the data received in WM_TOUCH window messages rather than the Tablet PC API.

This is primarily intended to work around the WPF Touch Event Fires with Delay bug in WPF, particularly severe with multi-touch. However, this libary can be useful to enable other functions that require WM_TOUCH such as App-style focus tracking in Windows 8.

More information on this issue and solution is posted here.

Usage

• Call MessageTouchDevice.RegisterTouchWindow(IntPtr hWnd) during or after your Window's SourceInitialized event
• Call MessageTouchDevice.WndProc from a function you attach to your Window using HwndSource.AddHook
