RE: [GD-Windows] SetCursorPos on TabletPC

[George G. <ge...@ba...>]

While there may be differences when using DirectInput, for Win32 calls
the type of pointing device (tablet, light pen, trackball, etc) should
all result in a relatively predictable and 'mouse-centric' result.  For
example, WM_MOUSEMOVE returns the x/y position, not a change delta.  So
I wouldn't expect any differences in Win32 calls with different devices.
