The only change really is adding SE_MOUSE_ABS to sysEventType_t.
In theory this breaks the ABI, but in practice I don't think mods use
sysEventType_t, and certainly not the ones above SE_MOUSE
(SE_JOYSTICK_AXIS doesn't make sense as Doom3 never supported Joysticks,
SE_CONSOLE is for input from TTY or whatever, and doesn't make sense
for mods to use in any way)
The change in Stub_SDL_endian.h is just me being paranoid.
(side-note: it *might* make sense to replace all that inline-asm in
Stub_SDL_endian.h with compiler intrinsics like GCC/clangs
__builtin_bswap* and MSVCs _byteswap_* - if they are supported in
all relevant compiler versions. GCC supports 32 and 64 bit swaps since
4.3, 16bit since 4.8 and 128bit since 11.x; clang supports 32 and
64 bit swaps at least since 3.0 and 16bit swaps since 3.2;
VS introduced _byteswap_ushort, .._ulong and .._uint64 in VS2003)
This was only implemented with MSVC style asm.
Comments suggest that it was used to help catch invalid FOV calculations,
which were probably only happening with ancient compiler bugs.
Split fs_savepath for config files. This is in preparation for
moving the writable paths on *nix to $XDG_DATA_HOME and
$XDG_CONFIG_HOME.
Affected files: config.spec, *.cfg, doomkey, xpkey.
Sys_GetScanTable() and MapKey() are only used by the Windows backend
or the Windows-only tools.
Rename to Win_GetScanTable() and move MapKey() as Win_MapKey() to
win_input.cpp.
Get rid of the 2 CPUID flags and combine them with SSE in one
implementation.
SSE flags can now be set on all x86 and x86_64 platforms -
independent of -ffast-math.
Helper defines borrowed from STREFLOP.
Thread return types are different between platforms, and its
probably not a good idea to return something of a different size,
cast the callback and expect it to not crash.
Let scons link directly in the build folder.
Multiple archs can coexist next to each other.
New scons variable "X86" to cross compile x86 binaries on x86_64.
