tx32767.wad is a Doom texture wad that shows that a texture can contain
up to 32,767 patches, even though some tools like DeuTex and Wintex
enforce lower, arbitrary, limits.

This is how it was generated:

#
#	Makefile to generate a Doom texture wad that redefines STARTAN3
#	to use 32767 patches. You need DeuTex version 4.5 or later (not
#	released as of this writing), as version 4.4 limits the number
#	of patches per texture to 256.
