The stack is for data, not return addresses.

9501d30a8f Fix up a missing const attribute.
The problem with having such a complex build system :P

82809eb856 Simplify the call to PR_LoadProgsFile.
I've decided that setting pr.max_edicts and pr.zone_size as part of the
local progs initialization rather than in PR_LoadProgsFile makes more
sense. For one, it is unlikely for the limits to change every time progs is
reloaded. Also, they seem to be a property of the VM rather than the progs.
However, there is nothing stopping the caller from updating max_edicts and
zone_size every call.

34bcf7faab Do a pure/const/noreturn/format attribute pass.
I always wanted these, but as gcc now provides warnings for functions that
could do with such attributes, finding all the functions is much easier.

While some of the warnings were merely annoying, some where actual bugs or

546e333a3c Allow Sys_Error to be hooked.
This makes debugging builtins that wrap normal functions a little easier by
giving a progs dump when such an error occurs.

f0dc995c67 Handle c99 inline vs gnu89 inline.
The meaning of "extern inline" and "inline" swaps between the two, and
gcc-5 uses c99 inline.

d1f1375df5 Increase number of supported joystick buttons.
Also fix a bug where despite supporting 32 buttons, only 18 were actually
supported, and a similar issue for the number of axes.

My saitek x52 has 34 buttons and 10 axes. Whee.

9d71d9bb7a Remove maxwarpwidth and maxwarpheight.
Only the sw32 renderer even tried to use them, and they didn't get set
properly. This fixes JohnnyonFlame's waterwarp issue.

8bea6a66ca Create _QFS_VOpenFile and QFS_VOpenFile.
_QFS_VOpenFile is actually _QFS_FOpenFile reimplemented to take vpath start
and end parameters so the search can be limited. QFS_VOpenFile,
_QFS_FOpenFile, and QFS_FOpenFile are all wrappers for _QFS_VOpenFile.

3efb0c538f Separate file search from loading.
QFS_LoadFile (and its wrappers) now  take a file handle rather than a
path. This will make vpath usage a little cleaner to implement.

a561477274 Nuke QFS_LoadStackFile().
It was used in only one place and is really not necessary (these days,
anyway).

25a060f369 Remove the foundname param from _QFS_FOpenFile.

576c73cf7c Replace qfs_file_from_pak with qfs_foundfile.

vpath.

a5db0b1a65 Remove the now unnecessary GLSL_CompileShaderS().
Now that the transition to using shader effects is comlete, there's no

96c40cb9a1 Add basic support for shader "effects".
Again, based on The OpenGL Shader Wrangler. The wrangling part is not used
yet, but the shader compiler has been modified to take the built up shader.
Just to keep things compiling, a wrapper has been temporarily created.

d912970cd3 Add support for segmented text files.
The idea comes from The OpenGL Shader Wrangler
(http://prideout.net/blog/?p=11). Text files are broken up into chunks via
lines beginning with -- (^-- in regex). The chunks are optionally named
with tags of the form: [0-9A-Za-z._]+. Unnamed chunks cannot be found.
Searching for chunks looks for the longest tag that matches the beginning
of the search tag (eg, a chunk named "Vertex" will be found with a search
tag of "Vertex.foo"). Note that '.' forms the units for the searc
("Vertex.foo" will not find "Vertex.f").

Unlike glsw, this implementation does not have the concept of effects keys
as that will be separate. Also, this implementation takes strings rather
than file names (thus is more generally useful).

247f3be0c0 Create reentrant versions of the set functions that need it.

27bb337a60 Use set_bits_t for holding set elements.
set_bits_t is now 64 bits for x86_64 machines (in linux, anyway). This gave
qfvis a huge speed boost: from ~815s to ~720s.

Also, expose some of the set internals so custom set operators can be
created.

6eec76dd49 Implement Fischer's SEB algorithm (for 3d).
Now we can get tight (<1e-6 * radius_squared error) bounding spheres. More
importantly (for qfvis, anyway) very quickly: 1.7Mspheres/second for a 5
point cloud on my 2.33GHz Core 2 :)

b6d4766201 Add a function to find the circumsphere of up to 4 points.
It seems to be a little sloppy (an error of a bit less than 1e-4). This
might be why I'm having trouble with my SEB code.

0cd6d93030 Add a function to get the barycentric coords of a point.
It "works" for lines, triangles and tetrahedrons. For lines and triangles,
it gives the barycentric coordinates of the perpendicular projection of the
point onto to features. Only tetrahedrons are guaranteed to reproduce the
original point.

ca0b03687f Change the naming of ALLOC's free-list.
Rather than prefixing free_ to the supplied name, suffix _freelist to the
supplied name. The biggest advantage of this is it allows the free-list to
be a structure member. It also cleans up the name-space a little.

cb025838aa Fix a silly error in QF/alloc.h's FREE.
FREE was effectively a nop :P This fixes the crazy memory leak in qfvis.

eb2828e11c Add a function to pre-allocate space for a large set.
When the maximum set size is large but constant, and members will be added
one at a time, growing the set dynamically is not very efficient.

7c1d9d2b84 Make the angle and light hacks optional.
I'd forgotten that ED_ConvertToPlist mangled light into light_lev and
single component angle values into a vector. This fixes much of the
breakage in qflight (but not the light levels)

675db274a6 Use Sys_Error instead of PR_Error in ED_ConvertToPlist.
ED_ConvertToPlist is now independent of the progs engine as its only use
for the progs_t * param was for PR_Error.

8e86ce9de9 Implement Sys_LongTime and wrap it with Sys_DoubleTime.
Sys_LongTime returns time in microseconds as a 64-bit int. Sys_DoubleTime
uses Sys_LongTime, converts to double and offsets 0 time by 4G (2**32).
This gives us consistent sub-microsecond precision for a very long time.

x/y/z and pitch/yaw/roll (or p/y/r). Johnny's numbers still work, too, of
course.

b2e92c2864 Rewrite joy_axis and JOY_Move for axis buttons.
First, this completely smashes joystick input: it will not work (though it
doesn't crash). This is because there is, as of yet, no means to configure
the system.

Each joystick axis has:
    - per-axis amplification (both pre and post).
    - per-axis offset (offset applied after pre-amp but before post amp)
    - selectable destination:
        - linear delta: position and angles (as before)
        - axis button: if the value crosses the threshold, the given key is
          pressed or released as appropriate.

The axis amplification still uses joy_amp and joy_pre_amp (and
in_amp/in_pre_amp), but now also has the per-axis settings.

The per-axis offset is most useful for axis buttons. For example, the xbox
360 controller triggers are analong but go "all the way to negative on 0
state". Offsetting the input keeps axis button thresholds simple.

Amplification and offset is applied before anything is done with the axis
value. The formula is:

    joy_amp * in_amp * axis-amp *
        (offset + value * joy_pre_amp * in_pre_amp * axis-pre_amp)

Axis button thresholds are very simple: if the sign of the value is the
same as the sign of the threshold and abs(value) >= abs(threshold), the
button is pressed. While multiple thresholds and keys can be placed on an
axis, only one can be pressed at a time. The threshold furthest from 0
wins.
