Timo : brush primitive texturing
the brushprimit_texdef given must be understood as a qtexture_t width=2 height=2 ( HiRes )
Timo : texture plugin, added an IPluginTexdef* parameter
must be casted to an IPluginTexdef!
if not NULL, get ->Copy() of it into each face or brush ( and remember to hook )
if NULL, means we have no information, ask for a default
