Fixed crash if initialization of EGL failed but was tried again later.

Browse Source 
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().

// 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. For now, however, the system-reported values are sent
// to SDL with minimal transformation: from native screen coordinates (in DIPs)
// to SDL window coordinates.
