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.
The way I wound up using the field meant that exprctx should not "own"
the hashlinks chain, but rather just point to it. This fixes the nasty
access errors I had.
Dependencies on vkparse.hinc were spreading through the code which I
didn't want as that removes a lot of the automation from the automake
files. This keeps all parser code internal to vkparse.c's scope, and any
accesses required for enum and struct (not yet) definitions can be
fetched by name.
I had forgotten that msaa samples was governed by the driver (as a max)
and the renderpass setup code simply took the max. Thus why 1 vs 8
caused the display to render incorrectly.
It turned out the msaa setting defaulting to 1 instead of 8 was the
problem no idea why at this stage (need to read up on just how that
setting works). Once I understand just how it works, I'll rework the
msaa handling.
This gets renderpass parsing almost working (not hooked up, though). The
missing bits are support for expressions for flags (namely support for
the | operator) and references (eg $swapchain.format). However, this
shows that the basic concept for the parser is working.
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
