db8cf68ef3 [gamecode] Pass registered data pointer to builtins
This is the bulk of the work for recording the resource pointer with
with builtin data. I don't know how much of a difference it makes for
most things, but it's probably pretty big for qwaq-curses due to the
very high number of calls to the curses builtins.

Closes #26

c6aa061229 [qwaq] Fetch Ruamoko progs locals from the stack frame
Now that the data is fetched from the correct location, the locals view
is useful again :). However, there seems to be a problem with array
views: not sure they're showing the correct data as I was getting
unexpected values in the display but normal vars seem to be ok.

39583a959e [qwaq] Show only user local defs
While the .tmp defs weren't too much clutter in v6p progs, the .arg defs
in Ruamoko progs make for a lot of noise. Showing only user defs (those
without a leading .) makes for a much more usable locals display.

c10b09d41b [ruamoko] Make RUA_Sprintf more generally useful
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.

f4b81d30b0 [qwaq] Pass the correct selector when listeners respond
This is actually an old bug in qwaq that was masked by v6p progs
parameter passing: it was just luck that event got put in the correct
parameter and not trampled until the responder saw it. Ruamoko progs,
however, simply lost the event entirely because it never got explicitly
passed by the listener implementation.

ab8692bd96 [qwaq] Allow return values through forwarded messages
This was easy to achieve in v6p progs because all return values passed
through .return and thus could not be lost. However, Ruamoko progs use a
return pointer which can wind up pointed into the void (the return
buffer) and thus cause the return value to be lost. Using @return on
obj_msg_sendv bounces the return pointer through to the called function.
In addition, nil is returned when the forwarding target is nil.

f714b6fbea [qwaq] Up qwaq progs heap to 2MB
or 512kW (kilowatts? :P). Barely enough for vkgen to run (it runs out if
auto release is run during scan_types, probably due to fragmentation). I
imagine I need to look into better memory management schemes, especially
since I want to make zone allocations 64-byte aligned (instead of the
current 8). And it doesn't help that 16 words per allocation are
dedicated to the zone management.

Anyway, with this, vgken runs and produces sufficiently correct results
for the rest of QF to build, so long as qfcc is not optimizing.

bea1155e9e [qwaq] Give qwaq progs a stack of 64kB

e3f88b2b9c [qwaq] Align progs memory to 64 bytes

globals are properly aligned.

98215b46ad [ruamoko] Cast autoreleaseIMP to avoid ...
The ABI for the Ruamoko ISA set currently puts va_list into the
parameter stream whenever a varargs function is called. Unfortunately,
IMP is declared with ... and thus cannot be used directly unless all
methods become varargs, but I think that would cause even more
headaches.

9c51c3d2e1 [gamecode] Add a data pointer passed to builtin functions
This is part of the work for #26 (Record resource pointer with builtin
function data). Currently, the data pointer gets as far as the
per-instance VM function table (I don't feel like tackling the job of
converting all the builtin functions tonight). All the builtin modules
that register a resources data block pass that block on to
PR_RegisterBuiltins.

a6b932025c [gamecode] Provide builtins with information about their parameters
This will make it possible for the engine to set up their parameter
pointers when running Ruamoko progs. At this stage, it doesn't matter
*too* much, except for varargs functions, because no builtin yet takes
anything larger than a float quaternion, but it will be critical when
double or long vec3 and vec4 values are passed.

f72e8ef551 [qwaq] Fix a couple of errors in debug
Update qdb_get_string's mangling for qfcc's new unsigned int support and
fix an incorrect cast of the param pointer passed by prd_runerror that
caused a segfault when trying to use the string. Attempting to use
qwaq-app (ie, the qc debugger) on Ruamoko ISA progs mostly works, but
the defs are decidedly unhappy (due to the base registers).

4ae9474396 [ruamoko] Use pr_type_names for type sizes
short and ushort are "wrong" (1 instead of 0, because qfcc currently

cfe7c44df0 [gamecode] Rename ev_integer to ev_int

2df64384c1 [gamecode] Clean up string_t and pointer_t

8385046486 [qfcc] Warn when super dealloc invocation is missing
Forgetting to invoke [super dealloc] in a derived class's -dealloc

dcd1fa28ba [ruamoko] Get the input bindings working
With some hacks that are not included (plan on handling events and

working nicely: my little game is working again. While the trampoline

button listeners directly to Ruamoko instance methods proved to be quite
nice.

ad83422c56 [qwaq] Adapt startup code for use in a game engine
Until now, the new qwaq startup was used only in command-line tools and
console applications where things like Ruamoko security and having a
hunk were not an issue. Now the start up code (qwaq-*.c) can specify
that Ruamoko is to be secured and provide a hunk on a per-thread basis,
and the thread data is passed into the progs code via a progs resource.

d3853a2430 [qwaq] Update qwaq-x11's initialization
It now uses the advanced command line parsing used by qwaq-curses and
qwaq-cmd, but currently disables multi-threading (I don't want to deal
with threading in the engine just yet). The int file is -graphics
because qwaq-x11 is really just the X11 target, qwaq-win is built for
windows, but they use the same basic startup (I hope).

84a24dbb34 [renderer] Make R_RenderView private
This is actually a better solution to the renderer directly accessing
client code than provided by 7e078c7f9c.

Essentially, V_RenderView should not have been calling R_RenderView, and
CL_UpdateScreen should have been calling V_RenderView directly. The
issue was that the renderers expected the world entity model to be valid
at all times. Now, R_RenderView checks the world entity model's validity
and immediately bails if it is not, and R_ClearState (which is called
whenever the client disconnects and thus no longer has a world to
render) clears the world entity model. Thus R_RenderView can (and is)
now called unconditionally from within the renderer, simplifying
renderer-specific variants.

3ac6d2aa22 [x11] Use barriers to trap the pointer in the window
This should be a much friendlier way of "grabbing" input, though I
suspect that using raw keyboard events will result in a keyboard grab,
which is part of the reason for wanting a friendly grab.

There does seem to be a problem with the mouse sneaking out of the
top-right and bottom-left corners. I currently suspect a bug in the X
server, but further investigation is needed.

52c5f0545b [input] Add broadcast event for application window changes

both together).

4898a44263 [console] Hook up new input system
This has smashed the keydest handling for many things, and bindings, but
seems to be a good start with the new input system: the console in
qw-client-x11 is usable (keyboard-only).

The button and axis values have been removed from the knum_t enum as
mouse events are separate from key events, and other button and axis
inputs will be handled separately.

keys.c has been disabled in the build as it is obsolute (thus much of
the breakage).

825d8b7a49 [input] Make a start on the new binding system
Input Mapping Tables are still at the core as they are a good concept,

72900fd16b [qwaq] Move input handling to its own thread
As it is now a completely separate sub-system, there is a bit of trouble
with mouse handling in that curses must be initialized before input for

nicely. I suspect the solution to the init order issue is to make have
the curses sub-system initialize the terminal input driver, at least for
mouse input (ie, maybe just enable/disable mouse handing).

The queues in the curses resources struct have been cleaned up and the

a91dac60d9 [input] Start work on improved input system
The common input code (input outer loop and event handling) has been
moved into libQFinput, and modified to have the concept of input drivers
that are registered by the appropriate system-level code (x11, win,
etc).

As well, my evdev input library code (with hotplug support) has been
added, but is not yet fully functional. However, the idea is that it
will be available on all systems that support evdev (Linux, and from
what I've read, FreeBSD).

54604d9aa2 [util] Make hunk (optionally) thread-safe
For now, the functions check for a null hunk pointer and use the global
hunk (initialized via Memory_Init) if necessary. However, Hunk_Init is
available (and used by Memory_Init) to create a hunk from any arbitrary
memory block. So long as that block is 64-byte aligned, allocations
within the hunk will remain 64-byte aligned.

49c3dacbbc [util] Rename set_size to set_count
After seeing set_size and thinking it redundant (thought it returned the
capacity of the set until I checked), I realized set_count would be a
much better name (set_count (node->successors) in qfcc does make much
more sense).

f18e1366ba [vulkan] Silence vkgen's debug output
It was hidden by qwaq-curses, but the switch to using qwaq-cmd made it
pretty obvious.

ae58a8ba5d [qwaq] Create a commandline-only version of qwaq
qwaq-curses has its place, but its use for running vkgen was really a
placeholder because I didn't feel like sorting out the different
initialization requirements at the time. qwaq-cmd has the (currently
unnecessary) threading power of qwaq-curses, but doesn't include any UI
stuff and thus doesn't need curses. The work also paves the way for
qwaq-x11 to become a proper engine (though sorting out its init will be
taken care of later).

Fixes #15.

e81d690b51 [input] Create QF input library using keys.c
This refactors (as such) keys.c so that it no longer depends on console
or gib, and pulls keys out of video targets. The eventual plan is to
move all high-level general input handling into libQFinput, and probably
low-level (eg, /dev/input handling for joysticks etc on Linux).

Fixes #8

The z-transform program is so I can test out my math and eventually

2572011a4b [qwaq] Fix various scrollbar related issues
The editor now uses the vertical scrollbar for handling mouse wheel
scrolling, thus keeping the scrollbar in sync.

Scrollbar index can now cover the full range (not sure why I had that
-1), and the potential divide by zero is avoided properly.

Thumb-tab now positioned properly when the range is 0.

f09810b595 [qwaq] Implement the remaining basic cursor motion
This gets all the basic cursor motion from my old editor working.
arrow keys: left/right/up/down char/line
home/end: beginning/end of line
page up/down

and ctrl versions where left/right are prev/next work, up/down skip over
indents, home/end are beginning/end of screen, and page up/down are
beginning/end of text.

75ce07a14c [qwaq] Implement home and end
Currently, home always moves the cursor to the very first column, but
I'm considering making it move the cursor to the first non-space
character of the line if it's not already there, otherwise to the first
column (ie, the cursor will toggle between the two positions if it's in
one of them).
