the script paths were wrong, on Linux they were like
"pak000.pk4/script/doom_util.script" while on Windows it's only
"script/doom_util.script".
Fixed idFileSystemLocal::OSPathToRelativePath() to skip ...pk4/
also fixed GCC compile error in Common.cpp
only override cmd->viewDef in RB_DrawView() if we're drawing the
primary view (which for several calculations before actual drawing
was set to the saved/locked render view)
Note that r_lockSurfaces is more useful with r_useScissor 0 (otherwise
there's black bars over the screen when moving) and r_shadows 0 (otherwise
areas that weren't visible when locking are black because the lights
there are skipped)
remaining bug: gui surfaces move around the screen when looking around
set(CMAKE_REQUIRED_LIBRARIES backtrace) tells our custom libbacktrace
availability check that it needs to link against libbacktrace.
Seems like it also tells other unrelated compiler-checks like for
-fvisibility=hidden to link against libbacktrace, so if it's not
available they fail as well.
Fixed by unsetting CMAKE_REQUIRED_LIBRARIES after the backtrace check.
While debian-based distros ship libbacktrace as part of libgcc,
apparently in Arch Linux and openSUSE (and possibly others) it's a
separate package, so I mantion it in the README as an (optional)
dependency now and made CMake print a warning if it's not found.
according to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100839
the real compiler flag enabling this bullshit isn't
-fexpensive-optimizations but -ffp-contract=fast which for some(*)
reason is default in optimized builds.
I think it's best to disabled that optimization globally in case it
also breaks other code (I really don't want to spend several days to
hunt such an idiot bug again). I really doubt it makes any measurable
performance difference.
As https://twitter.com/stephentyrone/status/1399424911328874499 says
that clang might also enable this in the future (though to =on instead
of =fast which should be a bit saner but would still break our code),
just set this option for all GCC-ish compilers incl. clang.
(*) the reason of course is that GCC developers don't develop GCC for
their users but to win idiotic SPEC benchmarks
Only happend if `ONATIVE` was enabled (or some other flag was set
that enables the FMA extension), the root cause was that the cross
product didn't return 0 when it should, but a small value < 0.
Caused some faces to be missing in maps compiled with dmap.

has lots of explanation.
I think this is a compiler bug, this commit works around it.
fixes#147
because of https://github.com/microsoft/vcpkg/issues/18098 people shouldn't use vcpkg (at least until they fix that)
libjpeg, libogg and libvorbis(file) aren't needed anymore, so mention that it's only needed for 1.5.1 and older
I'm gonna use it with libbacktrace - I'll need the path of the
executable before I can use idStr (and thus before I could call
Sys_GetPath(PATH_EXE, str)).
The problem was that the editors called ChoosePixelFormat() instead of
wglChoosePixelFormatARB() - and the normal ChoosePixelFormat() has no
attribute for MSAA, so if MSAA is enabled (by SDL2 which calls the wgl
variant), ChoosePixelFormat() will return an incomaptible format and
the editors don't get a working OpenGL context.
So I wrote a wrapper around ChoosePixelFormat() that calls the wgl variant
if available, and all the necessary plumbing around that.
While at it, removed the unused qwgl*PixelFormat function pointers and
supressed the "inconsistent dll linkage" warnings for the gl stubs
