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

Fixed bug 4903 - Lack of color multiply with alpha (SDL_BLENDMODE_MOD + SDL_BLENDMODE_BLEND) blending mode for all renderers
Konrad
This kind of blending is rather quite useful and in my opinion should be available for all renderers. I do need it myself, but since I didn't want to use a custom blending mode which is supported only by certain renderers (e.g. not in software which is quite important for me) I did write implementation of SDL_BLENDMODE_MUL for all renderers altogether.
SDL_BLENDMODE_MUL implements following equation:
dstRGB = (srcRGB * dstRGB) + (dstRGB * (1-srcA))
dstA = (srcA * dstA) + (dstA * (1-srcA))

Result for SDL_BLENDMODE_MOD:

Result for SDL_BLENDMODE_MUL:

I think I did cover all possibilities within included patch, but I didn't write any tests for SDL_BLENDMODE_MUL, so it would be lovely if someone could do it.

Fixed bug 4484 - use SIMD aligned memory for SDL_Surface
Surfaces are allocated using SDL_SIMDAlloc()
They are marked with SDL_SIMD_ALIGNED flag to appropriatly free them with SDL_SIMDFree()
(Flag is cleared when pixels is free'd in RLE, in case user would hijack the pixels ptr)
When providing its own memory pointer (SDL_CreateRGBSurfaceFrom()) and clearing
SDL_PREALLOC to delegate to SDL the memory free, it's the responsability of the user
to add SDL_SIMD_ALIGNED or not, whether the pointer has been allocated with SDL_malloc() or
SDL_SIMDAlloc().

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().

Fixed bug 3023 - setting a white and then non-white texture color mod breaks the texture with software renderer
Adam M.
Okay, here is the problem, I think.
During the first blit, RLEAlphaSurface is called to do RLE conversion of the RGBA source into a format allowing it "to be quickly alpha-blittable onto dest". Since the destination is the screen, it has no alpha channel. RLEAlphaSurface calls copy_opaque(dst, src + runstart, len, sf, df) (where copy_opaque is copy_32), which has this code:
SDL_RLEaccel.c:984:
RGBA_FROM_8888(*src, sfmt, r, g, b, a);
PIXEL_FROM_RGBA(*d, dfmt, r, g, b, a);
On the first line, it reads the source pixel 0xFFFFFFFF. The second line drops the alpha value (because dfmt for the screen has no alpha channel) and writes 0x00FFFFFF. Later, when the RLE conversion is being undone, uncopy_32 is called, which has the following code:
SDL_RLEaccel.c:1001:
Uint32 pixel = *s++;
RGB_FROM_PIXEL(pixel, sfmt, r, g, b);
a = pixel >> 24;
PIXEL_FROM_RGBA(*dst, dfmt, r, g, b, a);
However, the the alpha channel has already been dropped by copy_opaque (= copy_32), so pixel = 0x00FFFFFF and 'a' becomes 0. Thus, all opaque pixels lose their alpha channel when being unRLE'd. (I don't know what happens to pixels with alpha from 1-254, but they should be checked too.)
So, that seems to be the problem, but I'm not sure what the solution should be. Since opaque pixels have alpha == 255, I'm thinking to create another uncopy function for opaque pixels that simply uses 255 for alpha.
However, there may be other problems here. For translucent pixels, uncopy_32 assumes the alpha channel is stored in the upper 8 bits, but copy_32 doesn't store it there. Instead, it stores it in whatever location is appropriate for the destination surface. Isn't one of their behaviors incorrect, given the other? I'm not sure which to change, however.
For translucent pixels, it seems that the blit function uses do_blend, which is the BLIT_TRANSL_888 macro, which also assumes alpha is in top 8 bits. It has the comment "we have made sure the alpha is stored in the top 8 bits...", but it seems that's not true (copy_32 doesn't make sure the alpha goes there).
Perhaps the correct fix is to make copy_32 put the alpha there, but then that seems to require that RLE conversion be limited to destination surfaces that don't use the upper 8 bits. However, looking further, it seems that has already been done: if (masksum != 0x00ffffff) return -1; /* requires unused high byte */

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.

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.

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).

[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.

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.
