There were lots of places in the code that called Sys_GrabInput(),
some of them each frame.
Most of this is unified in events.cpp now, in handleMouseGrab() which
is called once per frame by Sys_GenerateEvents() - this makes reasoning
about when the mouse is grabbed and when not a lot easier.
Sys_GrabInput(false) still is called in a few places, before operations
that tend to take long (like loading a map or vid_restart), but
(hopefully) not regularly anymore.
The other big change is that the game now uses SDLs absolute mouse mode
for fullscreen menus (except the PDA which is an ugly hack), so the
ingame cursor is at the same position as the system cursor, which
especially helps when debugging with `in_nograb 1` and should also help
if someone wants to integrate an additional GUI toolkit like Dear ImGui.
If a key is pressed whichs SDL_Keycode isn't known to Doom3 (has no
corresponding K_* constant), its SDL_Scancode is mapped to the
corresponding newly added K_SC_* scancode constant.
I think I have K_SC_* constants for all keys that differ between
keyboard layouts (which is mostly printable characters; F1-F12, Ctrl,
Shift, ... should be the same on all layouts, which means that e.g.
SDL_SCANCODE_F1 always belongs to SDLK_F1 which the old code already
maps to Doom3's K_F1).
What's extra nice (IMO) is that when Doom3 requests a *localized* name
of the key (like for showing in the bindings menu), we actually use the
name of the SDL_Keycode that *currently* belongs to the scancode, and
esp. the "Western High-ASCII characters" (ISO-8859-1) supported by Doom3
like Ä or Ñ are displayed correctly.
(I already implemented a very similar hack in Yamagi Quake II and
reused the list of scancodes)
This should fix most of the problems reported in #323
Added Sys_FreeClipboardData(char*) so I don't have to copy the string
from SDL_GetClipboardText() into a Mem_Alloc() buffer, but can just
do the right thing per platform, which in case of POSIX/SDL2 is
SDL_free().
SDL1.2 doesn't have clipboard support, otherwise I'd have removed all
platform-specific implementations and used SDL_Get/SetClipboardText()
everywhere (IIRC AROS only supports SDL1.2?)
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.
