   392   the driver or emulated through ANGLE)
   393 * Added a hint SDL_HINT_VIDEO_WIN_D3DCOMPILER to specify which D3D shader compiler to use for OpenGL ES 2 support through ANGLE
   394 * Added a hint SDL_HINT_VIDEO_WINDOW_SHARE_PIXEL_FORMAT that is useful when creating multiple windows that should share the same OpenGL context.
   395 * Added an event SDL_RENDER_TARGETS_RESET that is sent when D3D9 render targets are reset after the device has been restored.
   397 Mac OS X:
   398 * Added a hint SDL_HINT_MAC_CTRL_CLICK_EMULATE_RIGHT_CLICK to control whether Ctrl+click should be treated as a right click on Mac OS X. This is off by default.
   400 Linux:
   401 * Fixed fullscreen and focused behavior when receiving NotifyGrab events
   402 * Added experimental Wayland and Mir support, disabled by default
   404 Android:
   405 * Joystick support (minimum SDK version required to build SDL is now 12, 
   406   the required runtime version remains at 10, but on such devices joystick 
   407   support won't be available).
   408 * Hotplugging support for joysticks
   409 * Added a hint SDL_HINT_ACCELEROMETER_AS_JOYSTICK to control whether the accelerometer should be listed as a 3 axis joystick, which it will by default.
   412 ---------------------------------------------------------------------------
   413 2.0.1:
   414 ---------------------------------------------------------------------------
   416 General:
   417 * Added an API to get common filesystem paths in SDL_filesystem.h:
   418     SDL_GetBasePath(), SDL_GetPrefPath()
   419 * Added an API to do optimized YV12 and IYUV texture updates:
   420     SDL_UpdateYUVTexture()
   421 * Added an API to get the amount of RAM on the system:
   422     SDL_GetSystemRAM()
   423 * Added a macro to perform timestamp comparisons with SDL_GetTicks():
   424     SDL_TICKS_PASSED()
   425 * Dramatically improved OpenGL ES 2.0 rendering performance
   426 * Added OpenGL attribute SDL_GL_FRAMEBUFFER_SRGB_CAPABLE
   428 Windows:
   429 * Created a static library configuration for the Visual Studio 2010 project
   430 * Added a hint to create the Direct3D device with support for multi-threading:
   432 * Added a function to get the D3D9 adapter index for a display:
   433     SDL_Direct3D9GetAdapterIndex()
   434 * Added a function to get the D3D9 device for a D3D9 renderer:
   435     SDL_RenderGetD3D9Device()
   436 * Fixed building SDL with the mingw32 toolchain (mingw-w64 is preferred)
   437 * Fixed crash when using two XInput controllers at the same time
   438 * Fixed detecting a mixture of XInput and DirectInput controllers
   439 * Fixed clearing a D3D render target larger than the window
   440 * Improved support for format specifiers in SDL_snprintf()
   442 Mac OS X:
   443 * Added support for retina displays:
   444   Create your window with the SDL_WINDOW_ALLOW_HIGHDPI flag, and then use SDL_GL_GetDrawableSize() to find the actual drawable size. You are responsible for scaling mouse and drawing coordinates appropriately.
   445 * Fixed mouse warping in fullscreen mode
   446 * Right mouse click is emulated by holding the Ctrl key while left clicking
   448 Linux:
   449 * Fixed float audio support with the PulseAudio driver
   450 * Fixed missing line endpoints in the OpenGL renderer on some drivers
   451 * X11 symbols are no longer defined to avoid collisions when linking statically
   453 iOS:
   454 * Fixed status bar visibility on iOS 7
   455 * Flipped the accelerometer Y axis to match expected values
   457 Android:
   458 IMPORTANT: You MUST get the updated SDLActivity.java to match C code
   459 * Moved EGL initialization to native code 
   460 * Fixed the accelerometer axis rotation relative to the device rotation
   461 * Fixed race conditions when handling the EGL context on pause/resume
   462 * Touch devices are available for enumeration immediately after init
   464 Raspberry Pi:
   465 * Added support for the Raspberry Pi, see README-raspberrypi.txt for details
