f78aab1cb5 [vulkan] Create a render context
This gets an empty (no tasks or pipelines connected) render context
initialized and available for other subsystems to register their task
functions. Nothing is using it yet, but the test parse of rp_main_def
fails gracefully (needs those tasks).

91d9d0b251 [vulkan] Implement task parameter parsing
This should fill in the task function's parameters nicely. The parameter
count check is known to work.

2c3b89f722 [vulkan] Implement task function parsing
This just sets up the memory block and cexpr descriptors for the
parameters, parameter parsing is separate (and next). The parameters are
aligned to their size.

3fea31875c [vulkan] Get render pass inheritance working
Needed to add the render passes plitem to the cexr symbol table, too.
All that remains is to figure out how to deal with multiview (or really
@next) and get task parsing working.

cd1b20dc22 [vulkan] Get render info parsing mostly working
Just frame buffer and pipeline info to clean up before worrying about
tasks.

2287a3de3f [vulkan] Get render info parsing partially working
A bunch of missed struct members, incorrect parse types, and some logic
errors in the parse setup. Still not working due to problems with
vectors from plist string references and some other errors, but getting
there.

3498d8b2ae [vkgen] Add support for labeled array elements
This treats dictionary items as arrays ordered by key creation (ie, the
order of the key/value pairs in the dictionary is preserved). The label
is written to the specified field when parsing the struct. Both actual
arrays and single element "arrays" are supported.

061f90ab83 [vkgen] Add support for array element data
While I wound up not needing it in the end, it's now possible to specify
extra data for array element parsing.

9e050ebf9a [vulkan] Attempt to load the render info spec
It fails due to not supporting labeled arrays yet. I'm currently
thinking about the design for vkgen.

(getting this in now prevents the breakage).

e10b084d36 [vulkan] Generate parse data for new render pass structs
There's still a lot of work to do, but the basics are in. The spec will
be parsed into info structs that can then be further processed to
generate all the actual structs, generally making things a little less
timing dependent (eg, image view info refers to its image by name).

The new render pass and subpass structs have their names mangled for now
until I can switch over to the new system.

4cb120e878 [vulkan] Implement most of the changes for cube rendering
There are some missing parts from this commit as these are the fairly
clean changes. Missing is building a separate set of pipelines for the
new render pass (might be able to get away from that), OIT heads texture
is flat rather than an array, view matrices aren't set up, and the
fisheye renderer isn't hooked up to the output pass (code exists but is
messy). However, with the missing parts included, testing shows things
mostly working: the cube map is rendered correctly even though it's not
displayed correctly (incorrect view). This has definitely proven to be a
good test for Vulkan's multiview feature (very nice).

e1c4428c8e [vulkan] Set source item for cexpr errors

3603fa75cd [vulkan] Make Vulkan_CreateRenderPass more generally useful
It now lives in vulkan_renderpass.c and takes most of its parameters
from plist configs (just the name (which is used to find the config),
output spec, and draw function from C). Even the debug colors and names
are taken from the config.

e14e8050dc [vulkan] Remove vkparse.hinc from vkparse.h

08f33d2f3a [vulkan] Rename the renderpass files
I plan on moving the current hard-coded render pass creation from

convention).

78437c2c90 [vulkan] Parse VkRenderPass directly
QFV_CreateRenderPass doesn't support pNext and I don't particularly feel
like making it do so at this stage (tempted to remove it).

e5932d1f92 [vulkan] Support Vulkan's pNext in vkparse/vkgen
The real reason for the delay in implementing support for pNext is I
didn't know how to approach it at the time, but with the experience I've
gained using and modifying vkparse, the solution turned out to be fairly
simple. This allows for the use of various extensions (eg, multiview,
which was used for testing, though none of the hookup is in this
commit). No checking is done on the struct type being valid other than
it must be of a chainable type (ie, have its own pNext).

978d0306c0 [hash] Rename the publicly visible hashlink_t to hashctx_t
I think my biggest problem with the hashlink freelist parameter was how
much implementation it exposed in just the name.

b2d4fa0ccf [vulkan] Break render pass parsing away from swapchain
This allows a single render pass description to be used for both
on-screen and off-screen targets. While Vulkan does allow a VkRenderPass
to be used with any compatible frame buffer, and vkparse caches a
VkRenderPass created from the same description, this allows the same
description to be used for a compatible off-screen target without any
dependence on the swapchain. However, there is a problem in the caching
when it comes to targeting outputs with different formats.

eb4d566801 [vkparse] Add support for inheriting objects
It simply parses the referenced plist dictionary (via @inherit =
plist.path;) into the current data block, then allows the data to be
overwritten by the current plist dictionary. This may be a bit iffy for
any allocated resources, so some care must be taken, but it seems to
work nicely.

3a742f59f7 [vulkan] Copy array() parameters correctly
I had forgotten that the parameters are in reverse order, and even if I
had remembered, I forgot to reset offset before the second loop.
Pre-decrementing offset takes care of both issues at once.

cff23ac93c [vulkan] Connect up the cexpr library
This will make property list expressions easier to work with. The
library is rather limited right now (trig, dot, min/max/bound) but even
just min adds a lot of functionality.

8271860fb3 [vkgen] Add support for fixed arrays
I want to support reading VkPhysicalDeviceLimits but it has some arrays.
While I don't need to parse them (VkPhysicalDeviceLimits should be
treated as read-only), I do need to be able to access them in property
list expressions, and vkgen generates the cexpr type descriptors too.

However, I will probably want to parse arrays some time in the future.

928408bad9 [vulkan] Support multiple render passes
Multiple render passes are needed for supporting shadow mapping, and
this is a huge step towards breaking the Vulkan render free of Quake,
and hopefully will lead the way for breaking the GL renderers free as
well.

02ba3da0ba [vulkan] Ease writing of specialization data
While using binary data objects for specialization data works for bools
(as they can be 0 or -1), they don't work so well for numeric values due
to having to get the byte order correct and thus are not portable, and
difficult to get right.

Binary data is still supported, but the data can be written as a string
with an array(...) "constructor" expression taking any number of
parameters, with each parameter itself being an expression (though
values are limited at this stage).

Due to the plist format, quotes are required around the expression
("array(...)")

8b85e422d7 [vulkan] Add a debug stack to the vulkan instance
The stack is arbitrary strings that the validation layer debug callback
prints in reverse order after each message. This makes it easy to work
out what nodes in a pipeline/render pass plist are causing validation
errors. Still have to narrow down the actual line, but the messages seem
to help with that.
Putting qfvPushDebug/qfvPopDebug around other calls to vulkan should
help out a lot, tool.
As a bonus, the stack is printed before debug_breakpoint is called, so
it's immediately visible in gdb.

c29e9828b6 [vulkan] Clean up misuse of va for vulkan handles
The built up "path" name of the handle resource was not always surviving
the intervening call to cexpr_eval_string (in particular, when other
handles were created in the process of creating a handle). Rather than
simply increase the number of va buffers (where would it end?), just
regenerate the path when adding the new handle. It's probably quick
enough, and the code is not usually not on a critical path.

6fea5f5e1a [build] Add -Wformat-non-literal option
While this caused some trouble for pr_strings and configurable strftime
(evil hacks abound), it's the result of discovering an ancient (from
maybe as early as 2004, definitely before 2012) bug in qwaq's printing
that somehow got past months of trial-by-fire testing (origin understood
thanks to the warning finding it).
