Add rudimentary sanity checks when playing ANM files.
- Don't attempt to play an ANM file if it is empty (warn) or too short (error). - If failing to read IVF file header or initializing VPX codec, don't play ANM. - Return early from gltexapplyprops() if not in GL modes. git-svn-id: https://svn.eduke32.com/eduke32@3628 1a8010ca-5511-0410-912e-c29ae57300e0
