Add crunch support to radiant and q3map2, the submodule way
Includes !99 (closed) (Add crunch support to radiant and q3map2)
It makes crunch
a submodule, allowing us to easily get patches by just switching to newer commit references.
As in !99 (closed), the crnlib used to decode .crn
files is the one from Dæmon which is just the one by Unity made cross-platform. Since Unity brokes compatibility with BinomialLLC's legacy tree it's required to use either crunch from Dæmon or the one from Unity to compress textures that have to be read by radiant or q3map2.
I edited README
to add this mention.
