This fixes the problem of not finding files without a .gz extension when
gzip support is enabled (most of my quake data is compressed, so it took a
while for me to notice the problem).
The search for these files will stop in the vpath that contains the .bsp
file to which they belong. This will prevent problems with
id1/maps/start.lit being used for shadows/maps/start.bsp.
_QFS_VOpenFile is actually _QFS_FOpenFile reimplemented to take vpath start
and end parameters so the search can be limited. QFS_VOpenFile,
_QFS_FOpenFile, and QFS_FOpenFile are all wrappers for _QFS_VOpenFile.
A vpath is the union of all locations searched for a file in a single
gamedir (eg, shadows, id1 etc). This is a necessary step to preventing
problems like id1/maps/start.lit being used for shadows/maps/start.bsp.
However, QFS_FilelistFill still needs to be reworked as it does not compile
yet (testing was done with a gutted QFS_FilelistFill).
It seems mesa still has the bug where non-array attributes don't work
when set as attribute 0, and that the allocation order changed sometime
since I last tested with mesa. This fixes the black world and flickering
alias models on my eeepc.
So far, alias model rendering is the only victim, but things are working,
even if only color map lookup and fog blending are broken out at this
stage.
I expect the effect naming scheme will go through some changes until I'm
happy with it.
Again, based on The OpenGL Shader Wrangler. The wrangling part is not used
yet, but the shader compiler has been modified to take the built up shader.
Just to keep things compiling, a wrapper has been temporarily created.
The idea comes from The OpenGL Shader Wrangler
(http://prideout.net/blog/?p=11). Text files are broken up into chunks via
lines beginning with -- (^-- in regex). The chunks are optionally named
with tags of the form: [0-9A-Za-z._]+. Unnamed chunks cannot be found.
Searching for chunks looks for the longest tag that matches the beginning
of the search tag (eg, a chunk named "Vertex" will be found with a search
tag of "Vertex.foo"). Note that '.' forms the units for the searc
("Vertex.foo" will not find "Vertex.f").
Unlike glsw, this implementation does not have the concept of effects keys
as that will be separate. Also, this implementation takes strings rather
than file names (thus is more generally useful).
This is based on ccr's patch, but a little more thorough (he missed some
potential problems) and probably more readable (the original code wasn't
the greatest (still isn't, but...))..
It returns the rest of the line (minus // style comments) as the token. I
needed it in another project but this is my central repository for
script.py.
