Subject: [PATCH 02/25] Add support for (GLX|WGL)_EXT_swap_control_tear.

This required a small public API change: SDL_GL_SetSwapInterval() now accepts
 negative values, and SDL_GL_GetSwapInterval() doesn't report errors anymore
 (if it can't work, it'll return zero as a reasonable default).

If you need to test for errors, such as a lack of swap_control_tear support,
 check the results of SDL_GL_SetSwapInterval() when you set your desired
 value.

Subject: [PATCH 11/25] Fixed building on Mac OS X with Xcode 4.4 (OS X 10.8
 SDK).

I think you'll need to install Xquartz, the external-but-official replacement
 for Apple's X11, to get the Xlib headers: http://support.apple.com/kb/HT5293

Subject: [PATCH 12/25] Fixed bug 1564 - SDL has no function to open a screen
 keyboard on Android.

Philipp Wiesemann implemented a general on-screen keyboard API for SDL, and I switched iOS code over to use it.

 Notes -- Keyboard
 ==============================================================================
 
-SDL for iPhone contains several additional functions related to keyboard visibility.  These functions are not part of the SDL standard API, but are necessary for revealing and hiding the iPhone's virtual onscreen keyboard.
+The SDL keyboard API has been extended to support on-screen keyboards:
 
-int SDL_iPhoneKeyboardShow(SDL_Window * window) 
+int SDL_ShowScreenKeyboard(SDL_Window * window) 
 	-- reveals the onscreen keyboard.  Returns 0 on success and -1 on error.
-int SDL_iPhoneKeyboardHide(SDL_Window * window) 
+int SDL_HideScreenKeyboard(SDL_Window * window) 
 	-- hides the onscreen keyboard.  Returns 0 on success and -1 on error.
-SDL_bool SDL_iPhoneKeyboardIsShown(SDL_Window * window) 
+SDL_bool SDL_IsScreenKeyboardShown(SDL_Window * window) 
 	-- returns whether or not the onscreen keyboard is currently visible.
-int SDL_iPhoneKeyboardToggle(SDL_Window * window) 	
+int SDL_ToggleScreenKeyboard(SDL_Window * window) 	
 	-- toggles the visibility of the onscreen keyboard.  Returns 0 on success and -1 on error.

Subject: [PATCH 13/25] Fixed bug 1565 - some small GL context creation
 enhancements

Matthias Bentrup 2012-08-09 12:53:17 PDT

With OpenGL 4.3 the ARB added a new context flag for context reset isolation
and renamed the existing ES2 profile bit to ES profile bit, as it can be used
to request GLES 3 compatible contexts, too.

This patch adds these changes to SDL on Linux and Windows.

Also SDL lacks the ability to create shared contexts. This patch also adds a
new GL attribute to enable context sharing. As casting a GL context to int is
not portable, I added only a boolean attribute
SDL_GL_SHARE_WITH_CURRENT_CONTEXT, which makes the new context share resources
with the context current on the creating thread.

Subject: [PATCH 19/25] Fixed bug 1561 - BSD joystick: Increase the number of
 uhid devices to scan

Brad Smith 2012-08-01 20:10:19 PDT

The attached patch from the OpenBSD ports tree is to increase the number of
uhid devices to scan for joysticks. It's somewhat easy to exhaust the default
number of devices which are scanned.
