// HACK ALERT: TL;DR - Hiding the cursor in WinRT/UWP apps is weird, and
// a Win32-style cursor resource file must be directly included in apps,
// otherwise hiding the cursor will cause mouse-motion data to never be
// received.
//
// Here's the lengthy explanation:
//
// There are two ways to hide a cursor in WinRT/UWP apps.
// Both involve setting the WinRT CoreWindow's (which is somewhat analogous
// to a Win32 HWND) 'PointerCursor' property.
//
// The first way to hide a cursor sets PointerCursor to nullptr. This
// is, arguably, the easiest to implement for an app. It does have an
// unfortunate side-effect: it'll prevent mouse-motion events from being
// sent to the app (via CoreWindow).
//
// The second way to hide a cursor sets PointerCursor to a transparent
// cursor. This allows mouse-motion events to be sent to the app, but is
// more difficult to set up, as:
// 1. WinRT/UWP, while providing a few stock cursors, does not provide
// a completely transparent cursor.
// 2. WinRT/UWP allows apps to provide custom-built cursors, but *ONLY*
// if they are linked directly inside the app, via Win32-style
// cursor resource files. APIs to create cursors at runtime are
// not provided to apps, and attempting to link-to or use Win32
// cursor-creation APIs could cause an app to fail Windows Store
// certification.
//
// SDL can use either means of hiding the cursor. It provides a Win32-style
// set of cursor resource files in its source distribution, inside
// src/main/winrt/. If those files are linked to an SDL-for-WinRT/UWP app
// (by including them in a MSVC project, for example), SDL will attempt to
// use those, if and when the cursor is hidden via SDL APIs. If those
// files are not linked in, SDL will attempt to hide the cursor via the
// 'set PointerCursor to nullptr' means (which, if you recall, causes
// mouse-motion data to NOT be sent to the app!).
//
// Tech notes:
// - SDL's blank cursor resource uses a resource ID of 5000.
// - SDL's cursor resources consist of the following two files:
// - src/main/winrt/SDL3-WinRTResource_BlankCursor.cur -- cursor pixel data
// - src/main/winrt/SDL3-WinRTResources.rc -- declares the cursor resource, and its ID (of 5000)
//
const unsigned int win32CursorResourceID = 5000;

// Set 'PointerCursor' to 'blankCursor' in a way that shouldn't throw
// an exception if the app hasn't loaded that resource.

// 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 WinRT 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.
