The lightmaps aren't updated at all yet, so everything is static.
Figuring out how lightmap data gets to the gpu was a chore thanks to the
spaghetti in the bsp data, and then I'd forgotten that I was
pre-expanding the light data to rgb so wound up with weird lightmaps,
but without water or particles, demo1 is getting 5000fps at 800x450, and
it seems to be CPU limited.
Finally, quakeworld gets its *ahem* fancy skins. I'm not happy with how
skin loading is handled, but the whole model and skin support needs a
redesign.
Closes#74.
And further clean up skin api.
It turns out that skin functions must all be in the render libs, and
this results in Skin_Set (was Skin_SetSkin) needs to be accessed via a
function pointer rather than directly :(
This takes care of the double free and also cleans up a lot of the skin
api. However, the gl renderer lost top/bottom colors (for now). Vulkan
skins still don't work yet.
It should be much harder for a malicious server to crash the client
(there were a few holes in there still).
Also, set the fallback (server didn't specify) top/bottom colors to be
such that the default colors from the skin are used instead of white.
That is, those with more than 65520 vertices. Not properly supported for
sw or gl, and glsl isn't rendering properly for some reason (renderdoc
does see the meshes, though, so maybe depth or winding issues).
It was a right cow to get working at all due to the tangled mess of
dependencies between different hierarchies (switching to hierarchies as
components helpt), but other that some vertical positioning (paragraphs
and descenders), it's working fairly well now (and fairly quick other
than I think I need to ensure the shaping cache is used).
Some of them were actual leaks, but tracking memory should be a lot
easier now. However, there's a lot of room for optimization of
allocations (eg, recylcling of hierarchies. There is now 1 active
allocation (according to tracy) when nq exits: Qgetline's string buffer
(I think an api change is in order).
This makes it possible for hierarchies to clean themselves up (by
deleting their entities (though that will cause other problems later
when the hierarchy doesn't own the entities)), thus plugging a memory
leak when parsing passage text.
The main goal of this change was to make it easier to tell when a
hierarchy has been deleted, but as a side benefit, it got rid of the use
of PR_RESMAP. Also, it's easy to track the number of hierarchies.
Unfortunately, it showed how brittle the component side of the ECS is
(scene and canvas registries assumed their components were the first (no
long the case), thus the sweeping changes).
Centerprint doesn't work (but it hasn't for a while).
It's used for finding the entity that has the actual canvas component
attached. Useful for sharing a single canvas between multiple view
hierarchies, and worked as a proof of concept for doing similar with
hierarchy references, and might work for properly destroying canvas
items (fills etc) when a view entity is deleted (if attached to every
view).
This is for scroll boxes (the nesting of canvases is for the clipping
they provide). There are some issues with automatic layout, but this
gets things mostly working, in particular the management of the link
between hierarchies as a canvas is always the root of its hierarchy.
With the scroll box work I'm doing, I realized 16 bits is a little
cramped. Although I doubt it would be that much of a problem, switching
to 32 bits turned out to be free because of alignment.
Seems to work well. The other renderers have stubs because I don't feel
like implementing clipping for them. The gl and glsl wouldn't be too
difficult (need to handle the draw queues), but sw needs a fair bit of
work and I'm not sure it's worth the effort.
Much of the state handling was highly redundant (in particular, handling
entity and old_entity). This should make it easier to get dragable items
for window resizing.
This makes a possible improvement to e1m3, only barely affects ad_tears,
but makes about 30% difference to gmsp3v2 (21fps to 27, and from 3300
leafs to 2700).
