Sam Lantinga 0d24495b 2016-11-15T01:24:58 Removed unused constants Except for SDL_bmp.c where they are historically interesting and I've left them in.

Sam Lantinga 36e40d30 2016-10-11T23:19:05 Fixed bug 2923 - Add SDL_PIXELFORMAT_RGBA32 for byte-wise 32bit RGBA data Daniel Gibson Ok, I followed the simple approach of just making SDL_PIXELFORMAT_RGBA32 an alias of SDL_PIXELFORMAT_RGBA8888/SDL_PIXELFORMAT_ABGR8888, depending on endianess. And I did the same for SDL_PIXELFORMAT_ARGB32, .._BGRA, .._ABGR. SDL_GetPixelFormatName() will of course return SDL_PIXELFORMAT_RGBA8888 (or SDL_PIXELFORMAT_ABGR8888) instead of SDL_PIXELFORMAT_RGBA32, but as long as that's mentioned in the docs it shouldn't be a problem.
Sam Lantinga 27d4f099 2016-10-07T23:40:44 Implemented SDL_GetHintBoolean() to make it easier to check boolean hints
Sam Lantinga 9fff05f8 2016-10-01T11:29:13 Fixed bug 3352 - Adding alpha mask support to SDL_SaveBMP_RW Simon Hug The current SDL_SaveBMP_RW function that saves surfaces to a BMP uses an old bitmap header which doesn't officially support alpha channels. Applications just ignore the byte where the alpha is stored. This can easily be extended by using a newer header version and setting the alpha mask. The attached patch has these changes: - Extending the description of the function in the SDL_surface.h header with the supported formats. - Refining when surfaces get stored to a 32-bit BMP. (Must have bit depth of 8 or higher and must have an alpha mask or colorkey.) - Fixing a small bug that saves 24-bit BGR surfaces with a colorkey in a 24-bit BMP. - Adding code that switches to the bitmap header version 4 if the surface has an alpha mask or colorkey. (I chose version 4 because Microsoft didn't lose its documentation behind a file cabinet like they did with version 3.) - Adding a hint that can disable the use of the version 4 header. This is for people that need the legacy header or like the old behavior better. (I'm not sure about the hint name, though. May need changing if there are any rules to that.)

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().
