Just "loading" and "unloading" (both really just hints due to the
caching system), and an internal function for converting a handle to a
model pointer, but it let me test IQM loading and unloading in Vulkan.
I've run into a bit of an issue with transform management (really, just
need to make them owned by the scene, but that means creating a scene
for quake and quakeworld).
It now takes the function name to print in error message (passed on to
PR_Sprintf) and the argument number of the format string. The variable
arguments (in ...) are assumed to be immediately after the format
argument.
And create rua_game to coordinate other game builtins.
Menus are broken for key handling, but have been since the input rewrite
anyway. rua_input adds the ability to create buttons and axes (but not
destroy them). More work needs to be done to flesh things out, though.
For now, just bsearch (normal and fuzzy), qsort, and prefixsum (not in
C's stdlib that I know of, but I think having native implementations of
float and int prefix sums will be useful.
In testing variable fw/precision in PR_Sprintf, I got a nasty reminder
of the limitations of the current progs ABI: passing @args to another QC
function does not work because the args list gets trampled but the
called function's locals. Thus, the need for a va_copy. It's not quite
the same as C's as it returns the destination args instead of copying
like memcpy, but it does copy the list from the source args to a
temporary buffer that is freed when the calling function returns.
Other than its blocking of access to certain files, it really wasn't
that useful compared to the functions in qfs, and pointless with access
to qfs anyway.
The api hides all the gory details of message buffer setup and usage
(particularly the differences between writing and reading). Most
importantly, the api provides a safe way to read and write binary data
(always little endian).
