This gets the alias model render pass and pipeline passing validation.
I don't know why I didn't add the subpass field to the
VkGraphicsPipelineCreateInfo parser def, though it could be I simply
missed it, or I thought I wouldn't need it at the time.
After getting lights even vaguely working for alias models, I realized
that it just wasn't going to be feasible to do nice lighting with
forward rendering. This gets the bulk of the work done for deferred
rendering, but still need to sort out the shaders before any real
testing can be done.
It's not entirely there yet, but the basics are working. Work is still
needed for avoiding duplication of objects (different threads will have
different contexts and thus different tables, so necessary per-thread
duplication should not become a problem) and general access to arbitrary
fields (mostly just parsing the strings)
This necessitated hand-writing qfv_swapchain_t's descriptors as I don't
feel like getting that complicated with vkgen at this stage and it's not
really appropriate anyway? qfv_swapchain_t is meant to be read-only and
not parsed from a plist.
The prototypes for handle parsers needed to be changes because it turned
out "single" was inappropriate for handles as "single" allocates memory
for the parsed object, but handles must be written directly.
Nothing is actually done yet other than parsing the built-in property
list to property list items (the actual parser is just a skeleton), but
everything compiles
The property list specifies the base structures for which parser code
will be generated (along with any structures and enums upon which those
structures depend). It also defines option specialized parsers for
better control.
