57723b83 | 2019-10-24 21:13:05 | ARM: SIMD assembly optimization for function BlitRGBtoRGBPixelAlpha Much of the heavy lifting of this optimization is lifted from the Pixman project, which is distributed under an MIT-style license. As far as possible, these elements have been relicensed to the zlib license. | |

0e45984f | 2015-06-21 17:33:46 | Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI(). | |

b72938c8 | 2015-04-20 12:22:44 | Windows: Always set the system timer resolution to 1ms by default. An existing hint lets apps that don't need the timer resolution changed avoid this, to save battery, etc, but this fixes several problems in timing, audio callbacks not firing fast enough, etc. Fixes Bugzilla #2944. | |

b88ca1b4 | 2015-02-10 16:28:56 | the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802 | |

b48e54aa | 2015-01-26 22:00:29 | Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation Jonas Kulla The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c. I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along. | |

70438be2 | 2014-12-03 10:55:23 | WinRT: fixed bug whereby SDL would override an app's default orientation WinRT apps can set a default, preferred orientation via a .appxmanifest file. SDL was overriding this on app startup, and making the app use all possible orientations (landscape and portrait). Thanks to Eric Wing for the heads up on this! | |

24c86b55 | 2014-09-11 19:24:42 | [X11] Reconcile logical keyboard state with physical state on FocusIn since the window system doesn't do it for us like other platforms. This prevents sticky keys and missed keys when going in and out of focus, for example Alt would appear to stick if switching away from an SDL app with Alt-Tab and had to be pressed again. CR: Sam | |

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. | |

76b7b1e9 | 2013-08-16 09:20:33 | Fixed alpha composition when destination alpha is transparent. Jianyu Guan I found I make a big mistake that when dstA==0, I just simply let *dstp=*srcp and forgot to make dstRGB = srcRGB*srcA. The if consition "(*dstp & amask) == 0" in BlitRGBtoRGBPixelAlphaMMX and BlitRGBtoRGBPixelAlphaMMX3dNow should be removed. | |
|
89bc80f1 | 2013-08-16 06:59:19 | Fixed alpha blending for the MMX blit functions I see the Remarks of function SDL_BlitSurface shows that "when SDL_BLENDMODE_BLEND, we have dstA = srcA + (dstA * (1-srcA))". however, I tested some pictures but the result implies "dstA=arcA" actually. I stepped into the source code, and found after I set SDL_BLENDMODE_BLEND for the source surface, the final blit function is BlitRGBtoRGBPixelAlphaMMX when I use SDL_BlitSurface on my computer. And I found these codes: else if (alpha == amask) { /* opaque alpha -- copy RGB, keep dst alpha */ *dstp = (*srcp & chanmask) | (*dstp & ~chanmask); The same code is used in BlitRGBtoRGBPixelAlphaMMX3DNOW and BlitRGBtoRGBPixelAlpha. So I think they still keep dst alpha. Best regards, Jianyu Guan | |

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. |
