Calculate radius for alias models as well as brush.
Culling is no longer optional on alias models (was only ever disabled for viewmodel, which is a lot of extra effort to avoid clip testing 1 thing out of hundreds).
Clip QSG2 scaled alias models with a scaled bbox.
code into the sw model loading code, remove all refs to r_pixbytes from the
sw renderer (it was never anything but 1), kill libQFmodels_sw32, remove
all the 16 bit code from the 8 bit sw renderer.
create a field_offset macro that takes a structure type and a field and
returns the offset of the field within the structure
everything else:
use field_offset to calculate the size of variable sized structs
quakeio.h -> vfile.h
More diff reduction between trunk and my VFS code. Also took the time to
put some headers in order and fix a few #include's pointed out by moving
things around a bit.
add a crc field to aliashdr_t
model_alias.c:
set it for all models
cl_parse.c:
set the pmodel and emodel info keys to the crcs of the player and eye
models
r_local.h, r_shared.h, client.h and render.h at the same time (couldn't get
away from that:/) verly likely to be lots of breakage (eg, player and eye
models are NOT checksummed atm), but everything builds
