Short wrappers for Draw functins are in vid_render_vulkan.c so the
vulkan context can be passed on to the actual functions. The 2D shaders
are set up similar to those in glsl, but with full 32-bit color (rgba)
support instead of paletted. However, the textures are not loaded yet,
nor is anything bound.
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 tool is horrible as a built tool due to it not being silent when all
is good (it outputs the input file name) and sends its error messages to
stdout instead of stderr. Then filtering causes the error code to be
lost. This uses a solution found on stack-exchange.
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.
Array and single type overrides now allow the parsing of the items
themselves to be customized. This makes it easy to handle arrays and
pointers to single items while also using custom specifications, rather
than relying entirely on the custom override.
Block expressions hide ex_error, but get_type() always returns null when
it finds one (which it does by recursing into block expression), so just
check the type itself.
I want to be able to use name references, but that requires string
items, so anything that would normally be dictionary or array (or
binary, even) would also need to accept string. This seemed to be the
cleanest solution. Any custom parser would then need to check the type
and act appropriately, but any inappropriate types have already been
pre-filtered by the standard parsers.
Care needs to be taken to ensure the right function is used with the
right arguments, but with these, the need to use qconj(d|f) for a
one-off inverse rotation is removed.
