Sam Lantinga 3f1fd5ab 2023-05-23T10:59:03 Updated source to match SDL function prototype style
Sam Lantinga 0479df53 2023-01-09T09:48:21 Updated copyright for 2023
Sam Lantinga b8d85c69 2022-11-30T12:51:59 Update for SDL3 coding style (#6717) I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base. In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted. The script I ran for the src directory is added as build-scripts/clang-format-src.sh This fixes: #6592 #6593 #6594 (cherry picked from commit 5750bcb174300011b91d1de20edb288fcca70f8c)

Sylvain ab0cf42a 2021-03-04T14:33:56 Software nearest scaling: start at the middle of pixel so that it matches opengl GL_NEAREST mode most of the time
Sylvain Becker 9d707113 2021-01-30T20:09:35 Revert checks on destination scaling size (see bug #5510)
Sylvain Becker d6a6662f 2021-01-29T20:34:20 Remove checks on destination scaling size (see bug #5510)

Sylvain Becker dd6e02df 2021-01-28T11:03:45 SDL_stretch: remove un-used vars, same notation as blit functions
Ozkan Sezer 87f09007 2021-01-28T00:11:24 SDL_LowerSoftStretchLinear: assign result from scale_mat() to ret. otherwise it would always return -1 when SSE and NEON instrinsics are absent.
Sam Lantinga 24d6fda2 2021-01-27T12:50:09 Fixed bug 3816 - asm code in video/SDL_stretch.c Sylvain I propose this new version for SDL_stretch.c that drops mprotect and asm Code is similar to the StretchLinear, but the steps computation are kept similar to the nearest. so that: - it's pixel perfect with nearest - as fast as asm I think - no asm, nor mprotect - benefit for all archicture
Sam Lantinga 06ad887f 2021-01-27T11:39:03 Fixed bug 3816 - asm code in video/SDL_stretch.c Ozkan Sezer - adds MSVC __declspec(align(x)) support, - disables asm if PAGE_ALIGNED no macro is defined, - still disables asm for gcc < 4.6, need more info, - drops Watcom support.
Sylvain Becker 5e3cf0d1 2021-01-27T09:34:23 SDL_SoftStretch: disable asm path if mprotect isn't available (see bug #3816)

Sam Lantinga 9a73909b 2017-09-09T08:20:56 Fixed bug 3808 - fix a typo in SDL_stretch.c Ozkan Sezer The following patch fixes a minor _MSC_VER typo in SDL_stretch.c, and also does a tiny tidy-up for assembly opcodes cpp checks.
Philipp Wiesemann 266816b4 2017-03-26T21:00:19 Removed newlines from error messages.

Philipp Wiesemann 0e45984f 2015-06-21T17:33:46 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().

Ryan C. Gordon b72938c8 2015-04-20T12:22:44 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.
Alex Szpakowski fe6c797c 2015-04-10T23:30:31 Fixed an iOS view orientation issue when SDL_GL_CreateContext or SDL_CreateRenderer is called.
Edward Rudd b88ca1b4 2015-02-10T16:28:56 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
Philipp Wiesemann b48e54aa 2015-01-26T22:00:29 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.
David Ludwig 70438be2 2014-12-03T10:55:23 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!
Philipp Wiesemann 9c398852 2014-11-22T22:20:40 Corrected header file documentation comment.
Pierre-Loup A. Griffais 24c86b55 2014-09-11T19:24:42 [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
David Ludwig 3dcb451f 2014-04-09T21:29:19 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.
Sam Lantinga 58edac3e 2014-02-02T00:53:27 Fixed bug 2374 - Update copyright for 2014... Is it that time already??
Gabriel Jacobo f848adff 2013-11-29T10:06:08 Improve Android pause/resume behavior.
Ryan C. Gordon 7e1289af 2013-11-24T23:56:17 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.
Gabriel Jacobo 1e49b1ed 2013-08-21T09:47:10 OCD fixes: Adds a space after /* (glory to regular expressions!)
Gabriel Jacobo 695344d1 2013-08-21T09:43:09 OCD fixes: Adds a space before */
Gabriel Jacobo dad42067 2013-08-12T11:13:50 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.
Sam Lantinga 1ad936eb 2013-08-11T19:56:43 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.
