VP8 video playback as (side-by-side) replacement of ANM moving pictures.
Usage: For an ANM file <somefile>.anm/ANM, EDuke32 looks for <somefile>.ivf, which is the VP8 stream transported by an IVF container. It can be extracted from a WebM file with e.g. mkvextract tracks <filename>.webm 1:<filename>.ivf (part of Mkvtoolnix, the Matroska toolset) Libvpx is required, and the 'YUV'-->RGB conversion is implemented using a fragment shader, so it's for OpenGL modes only. Also, this commit doesn't enable the code. Unfinished: sound, aspect correction for fullscreen w/ non-square pixels, ... ? --- Make MAXNODESPERLINE in engine_priv.h actually a macro that depends on MAXYSAVES and MAXDIM instead of using the obsolete precomputed value. I think this might have been the cause for the latest patched-up overhead view crash. git-svn-id: https://svn.eduke32.com/eduke32@1933 1a8010ca-5511-0410-912e-c29ae57300e0
