Windows Phone 8.0 either did not define, or provide access to, a 'RoamingFolder'
or 'TemporaryFolder' for apps to use. Windows 8.0 and 8.1 do, as does
Windows Phone 8.1. This change allows SDL-based Windows Phone 8.1 apps to
access these folders, via either the SDL_WinRTGetFSPathUNICODE() or
SDL_WinRTGetFSPathUTF8() functions.
SDL_GetPrefPath(), which on WinRT, is based on SDL_WinRTGetFSPathUTF8(), will
continue to return the app's 'local' folder, despite Windows 8.x
counterpart apps using the 'roaming' folder, in order to preserve compatibility
when 8.0-based Phone apps upgrade to 8.1-based Phone apps.
This patch makes sure that any SDL_MOUSEBUTTONDOWN, SDL_MOUSEBUTTONUP, and
SDL_MOUSEMOTION events, as triggered by a touch event in a WinRT app, set the
event's 'which' field to SDL_TOUCH_MOUSEID. Previously, this was getting set
to the same value as events from a real mouse, '0'.
Thanks to Diego for providing information on this bug, and to Tamas Hamor for
sending over a patch!
