SDL 2.x recently accepted patches to enable OpenGL ES 2 support via Google's ANGLE library. The thought is to try to eventually merge SDL/WinRT's OpenGL code with SDL-official's.

Steps to reproduce:
1. Grab the cursor with SDL_SetCursorGrab()
2. Alt-tab away from the window
3. Click on the titlebar of the window
This will cause the window to disappear underneath the taskbar!
This appears to be a general issue with ClipCursor() on windows, i.e. I am getting the same behavior if I call ClipCursor() directly.
It is caused by a feedback loop between the ClipCursor function and the modal resize/move event loop that handles mouse-based sizing on Windows.
Lets Android take care of which is the primary pointer (the one acting as the
mouse in SDL), reorganized the Java side code as well to make it easier to
understand.
If your application wants to have access to the full resolution even when the system has DPI scaling enabled, call SetProcessDPIAware() before calling SDL_Init()
e.g.
typedef BOOL (WINAPI *SetProcessDPIAware_t)(void);
HMODULE hMod = LoadLibrary("user32.dll");
if ( hMod ) {
SetProcessDPIAware_t pSetProcessDPIAware = GetProcAddress( hMod, "SetProcessDPIAware" );
if ( pSetProcessDPIAware ) {
pSetProcessDPIAware();
}
FreeLibrary( hMod );
}
To enable this, set the environment variable SDL_MOUSE_RELATIVE_MODE_WARP to "1"
When mouse relative mode is disabled, put the cursor back where the application expects it to be, instead of where it was when relative mode was enabled.
Based on the original port to Wayland by: Joel Teichroeb, Benjamin Franzke, Scott Moreau, et al.
Additional changes in this commit, done by me:
* Wayland uses the common EGL framework
* EGL can now create a desktop OpenGL context
* testgl2 loads GL functions dynamically, no need to link to libGL anymore
* Assorted fixes to the Wayland backend
Tested on the Weston Compositor (v1.0.5) that ships with Ubuntu 13.10,
running Weston under X. Tests ran: testrendercopyex (all backends), testgl2, testgles2,testintersections

To keep the directory layout sane, we should probably move this one piece of source to the linux catch-all directory, instead of making it look like this is part of an SDL "input" subsystem.

The MMX path in SDL_fillrect.c uses the SSE intrinsic _mm_stream_pi. The function or symbol provided by the compiler will not be present because the SSE header may not get included. The linker will complain about an undefined reference.
Since this is the only intrinsic used here (and someone forgot to create one for MOVQ), I think the MMX path can be removed completely. At least I don't see another way to move 64-bits from an MMX register to memory.

On OS/X after calling SDL_SetWindowBordered right mouse clicks no longer register.
Steps to Reproduce:
1. Open a windowed window on OS/X. (With the border on.)
2. e.button.button will give values 1,2,3 depending on which mouse button I click.
3. Call SDL_SetWindowBordered to disable the border.
4. e.button.button will only give values 1,2. 3 (right mouse button) stops coming through.
Expected result:
I expect all mouse buttons to register.
"Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'backgroundWindows not nil in enterFullScreenTransitionWithOptions:animated:activatingIt:'"
To reproduce this, run testsprite2, press Alt-Enter once, again while it's animating to fullscreen, and then again while it's animating out of fullscreen.

Overview: While SDL_SetTextInputRect works perfectly to move my window out of the way of the virtual keyboard using SDL2/Android, on iOS this function has no effect.
Steps to Reproduce: Call SDL_SetTextInputRect with a rect near the bottom of the screen before calling SDL_StartTextInput.
Actual Results: The iOS virtual keyboard is displayed after calling SDL_StartTextInput, but the screen is not shifted to reveal the TextInputRect region.
Expected Results: The screen should be shifted to reveal the TextInputRect region (like with SDL2/Android.)
This patch implements SDL_SetTextInputRect for uikit/iOS.
It sets up notification handlers to respond to changes in the display of the keyboard. These handlers then change the frame of the view so it is moved out of the way of the keyboard as per SetTextInputRect.
This fixes behavior with the new Mac OS X fullscreen space code, as well as improve behavior on Linux desktops.
The default for normal fullscreen mode is still to minimize because we're likely doing a mode switch and don't want to stick around as a borderless window in the background.
I still haven't figured out why my application is being minimized when I try to raise, it but my previous workaround is causing issues.
For now the correct way to raise and/or restore the window is as follows:
if ( !(SDL_GetWindowFlags( window ) & SDL_WINDOW_MINIMIZED) )
{
SDL_RaiseWindow( window );
}
if ( SDL_GetWindowFlags( window ) & SDL_WINDOW_MINIMIZED )
{
SDL_RestoreWindow( window );
}
I will investigate the window state change rules more fully in the future.

When we get a kCGEventTapDisabledByTimeout or
kCGEventTapDisabledByUserInput, the event tap would perform an invalid
memory access. void pointers are so fun.
This code only runs if you explicitly build with SDL_MAC_NO_SANDBOX.

I encountered a problem trying to load a 8-bit paletted BMP file using SDL. This file was generated using GIMP 2.8. It has a big BITMAPINFOHEADER (0x6c bytes for biSize field), and thus the palette is incorrectly setup.

this patch adds support for the horizontal wheel in Windows. It is shamelessly copied off the vertical wheel code, but I guess that that is a value added in consistency.
Thanks to Denis Bernard!
Also, changed the Android manifest so the app doesn't quit with orientation
changes, and made testgles.c exit properly on Android.
A port of the ANGLE library (OpenGL ES 2.0 for Direct3D) to WinRT, via https://github.com/stammen/angleproject, is used as a base.
To enable, clone 'angleproject' into the directory one above where SDL/WinRT is, open the file SDL/include/SDL_config_winrt.h, and uncomment the #defines that begin with 'SDL_VIDEO_OPENGL'. From there, apps can create an OpenGL capable SDL_Window via the flag, SDL_WINDOW_OPENGL, and an OpenGL ES 2 context via SDL_GL_CreateContext. The Direct3D 11.1 renderer cannot be used alongside SDL_WINDOW_OPENGL. Only Windows 8/8.1 is supported for now. Shaders may need to be precompiled, in some (all?) cases.

I've recently tried to create multiple windows and process key events for them, and found that key events weren't being generated for most of the windows. After some investigating I've observed the following effects. All but the most recently created window experience these effects...
- a focus lost event is generated immediately after the focus gained event, even tho window still has focus
- key events report window id 0 rather than the id of the window which has focus, SDL thinks no window has focus?
- giving focus to a non SDL window and then selecting an SDL window causes events to be generated as expected, but only until focus changes again
Focus change events are queued and delayed (200 ticks) before they are dispatched. The problem occurs when a focus out and focus in event are received on the same tick. When these delayed events are dispatched they will be sent in the order determined by the window list rather than the order in which they are received.
The focus out dispatch is implemented by calling SDL_SetKeyboardFocus(NULL). This will remove focus from any window, regardless of whether it is the one originally targeted by the X11 event.
Since SDL_SetKeyboardFocus() will always dispatch a focus lost event as needed, the easiest solution is simply to only call SDL_SetKeyboardFocus(NULL) when SDL_GetKeyboardFocus() matches the target window.
The first bug had mouse motion events not getting sent out on non-touch devices, if and when a mouse button wasn't pressed.
The second bug caused virtual mouse motion events to get sent out-of-order on touch devices: the motion event would get sent after the touch occurred, rather than before.

I was going through the SDL_IntersectRectAndLine function and wondered to see the ComputeOutCode function implementation.
The problem in this algo is, x and y axis are getting check with respect to 0, Which is wrong, it should be get checked with respect to rectangle x and y axis.

The problem in question is caused by changeset 7771 (http://hg.libsdl.org/SDL/rev/5486e579872e / https://bugzilla.libsdl.org/show_bug.cgi?id=2121)
The redefinition of __inline__ (introduced by the addition of begin_code.h:128's "|| __STRICT_ANSI__") results in mingw's gcc throwing multiple
warning: always_inline function might not be inlinable [-Wattributes]
as well as a whole bunch of redefinitions of mingw internals which break linking of projects including the SDL2 headers.
This reverts http://hg.libsdl.org/SDL/rev/7cdeb64faa72 and fixes it in
the correct way. If you call SDL_SetWindowPosition on a fullscreen
window, it would update the x & y variables for the window, but not
actually move the window (since it was fullscreen). That would make the
internal state of the SDL_Window incorrect, causing
SDL_WarpMouseInWindow to offset incorrectly.
This makes it so SDL_SetWindowPosition updates the `windowed' x & y
coordinates, which take effect when you revert from fullscreen.
On Android available touch devices are now added with video initialization (like
the keyboard). This fixes SDL_GetNumTouchDevices() returning 0 before any touch
events happened although there is a touch screen available. The adding of touch
devices after a touch event was received is still active to allow connecting
devices later (if this is possible) and to provide a fallback if the new init
did not work somehow. For the implementation JNI was used and API level 9 is
required. There seems to be nothing in the Android NDK's input header (input.h)
to implement everything on C side without communication with Java side.
This is part of an overall effort to use the name, "WinRT", rather than "WindowsRT" (or "Windows RT"), as the shorthand name often seems to mean something different than the longhand name. (WinRT is an API, Windows RT is a product name)
This change removes some code that attempted to allow non-standard window sizes, the idea of which was to do display scaling, and a hackish one at that. If display scaling is needed, use SDL_Renderer as appropriate.
- moved SDL_WinRTApp.* from src/video/windowsrt/ to src/core/winrt/, and renamed them to SDL_winrtapp.* (to mimick case-sensitivity used elsewhere in SDL)
- renamed all "windowsrt" directories (in src) to "winrt", as the shorthand name is used more often (and, IMO, "WinRT" != "Windows RT", not entirely at least)

SetupWindowData in SDL_windowswindow.c doesn't initialize two members of SDL_WindowData with NULL. This is an issue because other parts of the SDL code seem to make the assumption that this is the case. WIN_DestroyWindowFramebuffer for example uses data->mdc and data->hbm if they're not NULL.
