b7ad02c71d [qfcc] Use float for v6 comparisons
While simple types used floats, functions, vectors and entities used
ints. This doesn't go so well when compiling for v6 progs.

67eb38173b [qfcc] Back out incorrect precedence check changes
The precedence check changes done in
63795e790b seem to have been incorrect
(game-source/ctf produced many false positives), so putting that check
against '=' back into the code seems like a good idea (no more false
positives). That sounds a bit cargo-cult, but I'm really not sure what I
was thinking when I did the changes (probably just tired).

a2b5ebde65 [qfcc] Treat parameter shadowing as an error
This applies only to the top-level scope of the function. I'm not sure
if it's right for traditional quakec code, but that can be adjusted
easily enough.

bc2204d446 [qfcc] Differentiate symtabs by intended use
The symtab code itself cares only about global/not global for the size
of the hash table, but other code can use the symtab type for various
checks (eg, parameter shadowing).

65e15c2dd0 [cexpr] Keep track of unidentified symbol names
At least with a push-parser, by the time the parser has figured out it
has an identifier, the lexer has forgotten the token, thus the annoying
and uninformative "undefined identifier " error messages. Since
identifiers should always have a value (and functions need a function
type), setting up a dummy symbol with just the identifier name
duplicated seems to do the trick. It is a bit wasteful of memory if
there are a lot of such errors between cmem resets, though.

d5b93c20b3 [plist] Pass array index/label to the parse function
I ran into the need to get at the label of labeled array element and the
best way seemed to be by setting the name field of the plfield_t item
passed to the parser function, and then found that PL_ParseSymtab
already does this. I then decided passing the array index would also be
good, and the offset field made sense.

35df90cb3f [ruamoko] Add qfot_basic_t to qfot_type_t
qfot_basic_t is necessary for getting at the width of basic value types
(int, uint, float, long, ulong, double) in order to distinguish between
scalars and vectors of those types.

I had forgotten this when doing the Ruamoko VM and qfcc changes.

fc7c96d208 [qfcc] Support C's full type system
Along with QuakeC's, of course. This fixes type typeredef2 test (a lot
of work for one little syntax error). Unfortunately, it came at the cost
of requiring `>>` in front of state expressions on C-style functions
(QuakeC-style functions are unaffected). Also, there are now two
shift/reduce conflicts with structs and unions (but these same conflicts
are in gcc 3.4).

This has highlighted the need for having the equivalent of the
expression tree for the declaration system as there are now several
hacks to deal with the separation of types and declarators. But that's a
job for another week.

The grammar constructs for declarations come from gcc 3.4's parser (I
think it's the last version of gcc that used bison. Also, 3.4 is still
GPL 2, so no chance of an issue there).

35f4f2e692 [qfcc] Move basic specifier creation into qc-lex
This simplifies type type_specifier rule significantly as now TYPE_SPEC
(was TYPE) includes all types and their basic modifiers (long, short,
signed, unsigned). This should allow me to make the type system closer
to gcc's (as of 3.4 as that seems to be the last version that used a
bison parser) and thus fix typeredef2.

5f22a322df [qfcc] Allow redefined typedefs if the same type

e974e9d758 [qfcc] Add some failing typedef redef tests
typeredef1 parses properly but fails due to it erroneously complaining
that foo is redeclared as a different kind of object (it's the same
kind).

typeredef2 is the real problem in that it's a syntax error when it
should not be. This has proven to be a show-stopper for development on
my laptop as it has very recent vulkan headers which have such a
duplicate typedef.

bc041d6291 [vulkan] Zero draw's frame structs
Some of the queues start don't get fully initialized, but rather than go
through everything making sure they do, it's just easier to zero the

3d52caadec [ecs] Avoid shuffling components in empty ranges
When bubbling a component past an empty range, there's no need for any
actual movement other than adjusting the range itself, and doing so
corrupts the sparse/dense array relationship. Fixes a segfault when
hiding the deathmatch overlay (that resulted from the change to using
canvases).

f0fab885d4 [ui] Get canvas into a usable state
Canvas_SortComponentPool now takes the raw canvas component id as it is
specialized to the canvas subpools.

Canvas_SetLen resizes the root view and then updates the hierarchy for
every canvas in the system.

Canvas_InitSys sets up the component system with the systems it needs
(canvas, view, text). This is required to ensure view_href is just past
the canvas components as it is needed for retrieving the actual canvas
component (and thus sub-pool range ids) from arbitrary views in the
canvas.

Entities are fetched with the correct offset from the pool entities.

68c7003991 [console] Separate loading and initialization

console before the console initializes. It already separates console
cvar setup and initialization, which has generally been a good thing.

d7b1fceb12 [vulkan] Remove a dead FIXME

b91a76cbcc [vulkan] Get Draw_TextBox working again
This needed either more font ids to be supported, or small lump pics (up
to 32 x 32) to be loaded into the atlas. I went with both. The menus
don't use Draw_TextBox, but quakeworld's netgraph does.

9349a739db [renderer] Run particle update in renderer update
This has little effect on sw/gl/glsl, but makes it so the particle

42441e87d4 [vulkan] Create a vulkan-specific UpdateScreen
The goal is to get vulkan relying on the "renderpass" abstraction, but
this gets vulkan up and running again, and even fixes the rendering
issues (in the end, getting canvas working wasn't required, but is still
planned).

07d5749a4e [renderer] Make the core of SCR_UpdateScreen dynamic
This is a bit of a hack to allow me to work on vulkan's screen update
"pipeline" without having to mess with the other renderers, since it
turns out they're (currently) fundamentally incompatible.

d2467f1424 [vulkan] Use dynamic descriptors for dynamic verts
When a pic needs dynamic vertices (eg, for sub-pics), a descriptor set
is allocated and updated if one has not been created for the pic. This
is done each frame: the descriptor sets are recycled (there currently is
rarely a need for more than a small handful of dynamic descriptors, so
64 should be plenty for now).

Unfortunately, due to the order of operations issue between draw items
getting queued and submitting commands to vulkan (the cause of the pics
not rendering correctly per 8fff71ed4b),
the validation layers complain (correctly) about the command buffers
being executed with updated descriptor sets. Getting the canvas system
up and running will fix that.

4e1ddaa964 [renderer] Add fitted pic rendering
The pic is scaled to fill the specified rect (then clipped to the
screen (effectively)). Done just for the console background for now, but
it will be used for slice-pics as well.

Not implemented for vulkan yet as I'm still thinking about the
descriptor management needed for the instanced rendering.

Making the conback rendering conditional gave an approximately 3% speed
boost to glsl with the GL stub (~12200fps to ~12550fps), for either
conback render method.

31c1420682 [client] Further decouple screen and console
The wording might seem a little odd, but cl_screen is really the full 2D
client HUD while the console is completely independent of the client and
shouldn't know that the client even exists. Ideally, the resize events
would be handled by the canvas system, to which end this is a small
step.

2383c12a4a [renderer] Move r_framecount update out of render_scene
This fixes the broken dynamic lighting in fisheye rendering. It does
mean that frustum culling of lit surfaces needed to be removed, but if
not doing frustum culling on lit surfaces was good enough for a P90,
it's probably good enough for an i7-6850K.
