This API and implementation comes from the Unreal Engine branch of SDL, which
originally called this "SDL_ConfineCursor".
Some minor cleanup and changes for consistency with the rest of SDL_video, but
there are two major changes:
1. The coordinate system has been changed so that `rect` is _window_ relative
and not _screen_ relative, making it easier to implement without having
global access to the display.
2. The UE version unset all rects when passing `NULL` as a parameter for
`window`, this has been removed as it was an unused feature anyhow.
Currently this is only implemented for X, but can be supported on Wayland and
Windows at minimum too.
We don't use it, it was a leftover from 1.2, I think, and it doesn't exist
on Solaris, so this should hopefully fix the build there.
This also means we don't need the configure/cmake checks for
SDL_VIDEO_DRIVER_X11_CONST_PARAM_XEXTADDDISPLAY, so that was removed also.
Fixes#1666.
- cmake, configure (CheckDLOPEN): --enable-sdl-dlopen is now history..
detach the dl api discovery from SDL_LOADSO_DLOPEN functionality.
define HAVE_DLOPEN. also define DYNAPI_NEEDS_DLOPEN (CheckDLOPEN is
called only for relevant platforms.)
- update SDL_config.in and SDL_config.cmake accordingly.
- SDL_dynapi.h: set SDL_DYNAMIC_API to 0 if DYNAPI_NEEDS_DLOPEN is
defined, but HAVE_DLOPEN is not.
- pthread/SDL_systhread.c: conditionalize dl api use to HAVE_DLOPEN
- SDL_x11opengl.c, SDL_DirectFB_opengl.c, SDL_naclopengles.c: rely
on HAVE_DLOPEN, not SDL_LOADSO_DLOPEN.
- SDL_config_android.h, SDL_config_iphoneos.h, SDL_config_macosx.h,
SDL_config_pandora.h, and SDL_config_wiz.h: define HAVE_DLOPEN.

The LINKER variable is set in configure.ac as either 'CC' or 'CXX'
where it is then passed to the created Makefile. This fails with
slibtool which can't find the 'CC' file and can be fixed by correctly
setting the LINKER variable to an actual Makefile variable like '$(CC)'
or '$(CXX)' instead. Presumably GNU libtool does some magic here to
hide the issue.
The $(objects) directory (usually build/) may not have been created by
the time the wayland-scanner protocol files are being compiled. The
$(gen) directory is explicitly made with mkinstalldir, but the final
object file (and gcc dependency files) need to go into $(objects).
For whatever reason, this only ever seemed to occur if --disable-shared
was set.
Note that this commit doesn't regenerate ./configure, as there were a
few unexplained, unrelated differences my version of autoconf created,
as as an autotools novice, I didn't want to poke that bear just yet.
This hopefully should fix#3689
AC_CHECK_HEADER() emits warnings when configuring for non-x86, because
the preprocessor check is OK but the compile check is not:
configure: WARNING: immintrin.h: present but cannot be compiled
configure: WARNING: immintrin.h: check for missing prerequisite headers?
configure: WARNING: immintrin.h: see the Autoconf documentation
configure: WARNING: immintrin.h: section "Present But Cannot Be Compiled"
configure: WARNING: immintrin.h: proceeding with the compiler's result
