Subject: Make the semantics of CL_VM_UpdateView more clear - if CSQC is loaded, it is required... 
X-Git-Tag: xonotic-v0.8.5~44
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=57b1147864bc8633d27dc8e36086023bc37bf3a6;p=xonotic%2Fdarkplaces.git

Make the semantics of CL_VM_UpdateView more clear - if CSQC is loaded, it is required to provide the CSQC_UpdateView function, and won't render a view if it does not call that, so we don't need to check its return value.
