If a program built against one version of SDL is run in an
environment where there is an earlier version of the SDL .so library
installed, the result varies depending on platform configuration; in
the best case, it won't start at all, at worst it aborts in the
middle of the user doing "something important" (systems implementing
lazy symbol resolution). verdefs on the other hand are always checked
on startup.
The dependency information present in programs and shared libraries
is not only of value to the dynamic linker, but also to a
distribution's package management. If the dynamic linker is able to
tell that a program is not runnable per the above, a package manager
is able to come to the same conclusion — and block the installation
of a nonfunctional program+library ensemble.
Because there are a lot more symbols than there are libraries (I am
going to throw in "10^4 to 1 or worse"), package managers generally
do not evaluate symbols, but only e.g. the SONAME, NEEDED and VERNEED
fields/blocks. Because the SONAME is the same between two SDL
versions like 2.0.24, and 2.0.26, everything rests on having verdefs.
This patch proposes the addition of verdefs.
In SDL3 we plan to make more use of shaders in the 2D render API, and this minimizes the number of platforms we have to consider for new features. OpenGL ES 2.0 or newer is supported on all modern iOS and Android devices.
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
The new protocol adds support for more native communication of
fractional scaling.
Everything in the wayland backend already existed only our fractional
scale was calculated implicitly through a combination of output size
guesswork for fullscreen windows.
This new protocol makes that explicit, providing a more robust solution
and a solution for non-fullscreen surfaces. The fallback code is still
left in place for now whilst compositors gain support.
- do not overwrite error message set by SDL_InitFormat (SDL_AllocFormat)
- set proper error message (Cocoa_Metal_CreateView)
- protect against allocation failure (UIKit_Metal_CreateView)
* Remove depth field from SDL_CreateRGBSurfaceWithFormat and SDL_CreateRGBSurfaceWithFormatFrom
* Removed unused 'flags' parameter from SDL_CreateRGBSurface and SDL_CreateRGBSurfaceWithFormat
* Removed unused 'flags' parameter from SDL_ConvertSurface and SDL_ConvertSurfaceFormat
This behavior more closely matches other platform where the window is borderless but still interacts with the window manager (e.g. task bar shows above it, it can be resized to fit within usable desktop area, etc.)
If you want a borderless window the size of the desktop that looks like a fullscreen window, then you should use the SDL_WINDOW_FULLSCREEN_DESKTOP flag.

`argv[0]`/`getexexname()` are not always absolute paths by default and can be modified to anything the developer wants them to be.
Consider using `readSymLink("/proc/self/path/a.out")` instead and `getexecname()` as the fallback, since the symlink will always be the correct absolute path (unless /proc is ot mounted, but it is by default on Solaris and Illumos platforms).

I ran this script in the include directory:
```sh
sed -i '' -e 's,#include "\(SDL.*\)",#include <SDL3/\1>,' *.h
```
I ran this script in the src directory:
```sh
for i in ../include/SDL3/SDL*.h
do hdr=$(basename $i)
if [ x"$(echo $hdr | egrep 'SDL_main|SDL_name|SDL_test|SDL_syswm|SDL_opengl|SDL_egl|SDL_vulkan')" != x ]; then
find . -type f -exec sed -i '' -e 's,#include "\('$hdr'\)",#include <SDL3/\1>,' {} \;
else
find . -type f -exec sed -i '' -e '/#include "'$hdr'"/d' {} \;
fi
done
```
