+Quick hack at a transcoder tool from VP3 to Theora
+
+I actually built the avi2vp3 tool with codeWarrior, but it should compile under
+VC as well. I have included a source avi file and the converted .vp3 output.
+Output is a file with some header info matching YUVMPEG, and for each frame: 
+
+FRAME header block matching YUV2MPEG
+long (Intel aligned) keyframeflag describing in frame is a keyframe
+long (Intel aligned) fsize storing frame size in bytes
+bytes[fsize] with binary frame data
+
+The transcode tool is a modification of the current encoder. PUt it into the
+win32/experimental subdirectory, and the paths should be correct. It produces
+an apparently valid theora stream, but outputs garbage data. The code is packing
+the binary frame data in a way that SHOULD work at least imo, but I am probably
+missing some initialization issue (or vp3 is not transcodable to theora).
