// DLudwig, 2012-12-28: On some systems, namely Visual Studio's Windows

// Simulator, as well as Windows 8 in a Parallels 8 VM, MouseEventArgs'

// MouseDelta field often reports very large values. More information

// on this can be found at the following pages on MSDN:

// - http://social.msdn.microsoft.com/Forums/en-US/winappswithnativecode/thread/a3c789fa-f1c5-49c4-9c0a-7db88d0f90f8

// - https://connect.microsoft.com/VisualStudio/Feedback/details/756515

//

// The values do not appear to be as large when running on some systems,

// most notably a Surface RT. Furthermore, the values returned by

// CoreWindow's PointerMoved event, and sent to this class' OnPointerMoved

// method, do not ever appear to be large, even when MouseEventArgs'

// MouseDelta is reporting to the contrary.

//

// On systems with the large-values behavior, it appears that the values

// get reported as if the screen's size is 65536 units in both the X and Y

// dimensions. This can be viewed by using Windows' now-private, "Raw Input"

// APIs. (GetRawInputData, RegisterRawInputDevices, WM_INPUT, etc.)

//

// MSDN's documentation on MouseEventArgs' MouseDelta field (at

// http://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.input.mouseeventargs.mousedelta ),

// does not seem to indicate (to me) that its values should be so large. It

// says that its values should be a "change in screen location". I could

// be misinterpreting this, however a post on MSDN from a Microsoft engineer (see:

// http://social.msdn.microsoft.com/Forums/en-US/winappswithnativecode/thread/09a9868e-95bb-4858-ba1a-cb4d2c298d62 ),

// indicates that these values are in DIPs, which is the same unit used

// by CoreWindow's PointerMoved events (via the Position field in its CurrentPoint

// property. See http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.input.pointerpoint.position.aspx

// for details.)

//

// To note, PointerMoved events are sent a 'RawPosition' value (via the

// CurrentPoint property in MouseEventArgs), however these do not seem

// to exhibit the same large-value behavior.

//

// The values passed via PointerMoved events can't always be used for relative

// mouse motion, unfortunately. Its values are bound to the cursor's position,

// which stops when it hits one of the screen's edges. This can be a problem in

// first person shooters, whereby it is normal for mouse motion to travel far

// along any one axis for a period of time. MouseMoved events do not have the

// screen-bounding limitation, and can be used regardless of where the system's

// cursor is.

//

// One possible workaround would be to programmatically set the cursor's

// position to the screen's center (when SDL's relative mouse mode is enabled),

// however Windows RT does not yet seem to have the ability to set the cursor's

// position via a public API. Win32 did this via an API call, SetCursorPos,

// however WinRT makes this function be private. Apps that use it won't get

// approved for distribution in the Windows Store. I've yet to be able to find

// a suitable, store-friendly counterpart for WinRT.

//

// There may be some room for a workaround whereby OnPointerMoved's values

// are compared to the values from OnMouseMoved in order to detect

// when this bug is active. A suitable transformation could then be made to

// OnMouseMoved's values. For now, however, the system-reported values are sent

// to SDL with minimal transformation: from native screen coordinates (in DIPs)

// to SDL window coordinates.
