While the libraries are probably getting a little out of hand, the
separation into its own directory is probably a good thing as an ECS
should not be tied to scenes. This should make the ECS more generally
useful.
This puts the hierarchy (transform) reference, animation, visibility,
renderer, active, and old_origin data in separate components. There are
a few bugs (crashes on grenade explosions in gl/glsl/vulkan, immediately
in sw, reasons known, missing brush models in vulkan).
While quake doesn't really need an ECS, the direction I want to take QF
does, and it does seem to have improved memory bandwidth a little
(uncertain). However, there's a lot more work to go (especially fixing
the above bugs), but this seems to be a good start.
Hierarchies are now much closer to being more general in that they are
not tied to 3d transforms. This is a major step to moving the whole
entity/transform system into an ECS.
It holds the data for a basic 3d camera (transform, fov, near and far
clip). Not used yet as there is much work to be done in cleaning up the
client code.
