both if GL pointparameters are used or not
(though depending on driver and hardware the pointparameters-based
particles *might* be always square or always round, regardless of
gl1_particle_square - that's driver-bugs which we can't fix, disable
pointparameters with `gl1_pointparameters 0` to work around it, or
just use the GL3 renderer)
r_lerp_list is to allow exceptions to r_2D_unfiltered (like for having
pixely UI in general, but filtered console background).
r_videos_unfiltered controls whether videos should be filtered or not
I also made r_nolerp_list CVAR_ARCHIVE, like users probably expect it.
because on MSVC it uses alloca() (or _malloca()) which mustn't be called
in loops, as the memory is only freed when returning from the function,
not when leaving the scope (or before the next loop iteration).
Instead do one "dry-run" iteration to figure out how big the array must
be at most, and then allocate it once before the loop with that size.
The easiest way to build this is to check out the dhewm3-libs project
(https://github.com/dhewm/dhewm3-libs/) to provide the dependencies
(SDL2, OpenAL, cURL) and set YQUAKE2LIBS accordingly, by passing
-DYQUAKE2LIBS=c:/path/to/dhewm3-libs/i686-w64-mingw32 to cmake.
I wouldn't really recommend building with MSVC - I just somehow made it
work and ignored all the warnings and I have no idea how portable the
resulting binaries are etc. For binaries you actually want to use, please
continue using MinGW-w64. Especially my workaround for VLAs (C99 variable
length arrays) is kinda fishy, particularly if those arrays are allocated
in a loop (that's inly done in ref_gl1.dll's code).
The only reason I did this is that I had to debug on Windows and, at least
for my specific bug, gdb didn't really work with binaries produced by
MingGW-w64 and MSVC's debugger works well with binaries produced by MSVC.
Currently requires VS 2019 16.8 or newer with C11 (/std:c11) because I
couldn't get YQ2_ALIGNAS_TYPE() to work with MSVC without _Alignas().
If we can get this to work, VS2015 or newer might suffice (but not older
versions, because their so called C standardlib didn't provide exotic
functions like snprintf()).
