	3dcb451f	2014-04-09 21:29:19		Added a README file regarding WinRT support To note, this file is currently formatted with CRLF line endings, rather than LF, to allow the file to be viewed with Notepad.
	b677d1d8	2014-03-10 19:59:06		Fixed Mac OS X OpenGL context creation to match other backends, where we only care about the actual version we request if it's 3.0 or newer or a special profile context. Eventually we'll probably move the version checking to higher level code and report the actual version of context that got created, but to avoid breakage we'll leave it like this for now.

	d76c2cc1	2014-01-30 12:30:40		Add a new hint SDL_HINT_VIDEO_WINDOW_SHARE_PIXEL_FORMAT that allows SDL_CreateWindowFrom() to set the pixel format of another SDL_Window (and also will set the SDL_WINDOW_OPENGL flag on the window created with SDL_CreateWindowFrom()). The reasoning behind this change is that source2 in -tools mode has a single OpenGL context that is used with multiple different windows. Some of those windows are created outside the engine (i.e. with Qt) and therefore we need to use SDL_CreateWindowFrom() to get an SDL_Window for those. The requirement for sharing an OpenGL context across multiple different windows is that each window has the same pixel format. To facilitate this, I now set SDL_HINT_VIDEO_WINDOW_SHARE_PIXEL_FORMAT for the main window before calling SDL_CreateWindowFrom(). When I do this, SDL_CreateWindowFrom() will: 1. Set the pixel format of the returned window to the same pixel format as this SDL_Window passed in with the hint 2. The flag SDL_WINDOW_OPENGL will be set on the new window so it can be used for OpenGL rendering. I only currently implemented this for Win32/WGL so implementing it for other platforms (i.e. X11) remains a TODO. CR: SamL Some pseudocode that shows how this is used in Source2: HWND hExternalHwnd; // HWND that was established outside of SDL // Create main window (happens inside platwindow.cpp) SDL_Window mainWindow = SDL_CreateWindow( , SDL_WINDOW_OPENGL .. ); // Create GL context, happens inside rendersystemgl SDL_GLContext onlyContext = SDL_GL_CreateContext( mainWindow ); // Now I need to create another window from hEternalHwnd for my swap chain that will have the same pixel format as mainWindow, so set the hint SDL_SetHint( SDL_HINT_VIDEO_WINDOW_SHARE_PIXEL_FORMAT, CFmtStr( %p, mainWindow) ); // Create the secondary window. This returned window will have SDL_WINDOW_OPENGL set and share a pixel format with mainWindow from the hint SDL_Window secondaryWindow = SDL_CreateWindowFrom( hExternalHwnd ); // To render to the main window: SDL_GL_MakeCurrent( mainWindow, onlyContext ); // Do some rendering to main window // To render to the secondary window: SDL_GLMakeCurrent( secondaryWindow, onlyContext ); // Do some rendering to secondary window
	87ad7a1c	2013-12-25 16:57:59		Fixed pointer from integer warning and bug if compiled without EGL.
	f848adff	2013-11-29 10:06:08		Improve Android pause/resume behavior.
	7e1289af	2013-11-24 23:56:17		Make internal SDL sources include SDL_internal.h instead of SDL_config.h The new header will include SDL_config.h, but allows for other global stuff.
	4abeed93	2013-11-22 14:19:52		Fixes compilation on Mingw.
	61959aa6	2013-11-22 13:24:53		OpenGL ES support for Windows
	360c3d85	2013-10-21 00:15:24		Better cleanup if OpenGL initialization fails
	0e699eb5	2013-10-20 21:18:05		Added SDL_GL_FRAMEBUFFER_SRGB_CAPABLE (thanks, David!). Fixes Bugzilla #1985.
	dad42067	2013-08-12 11:13:50		Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
	1ad936eb	2013-08-11 19:56:43		Fixed bug 2027 - Full-screen appears to be broken - hang in SDL_DestroyWindow() Rainer Deyke I'm running Linux Mint 15 with the Cinnamon window manager. SDL_DestroyWindow consistently locks up for me when the window if fullscreen.
