+ seperate animation index files to solve the following problems:
+
+ a) different timecodes within one file (like DTS/PTS, Timecode-Track,
+ "implicit" timecodes within DV-files and HDV-files etc.)
+ b) seeking difficulties within ffmpeg for files with timestamp holes
+ c) broken files that miss several frames / have varying framerates
+ d) use proxies accordingly
+
+ ... we need index files, that provide us with
+
+ the binary(!) position, where we have to seek into the file *and*
+ the continuous frame number (ignoring the holes) starting from the
+ beginning of the file, so that we know, which proxy frame to serve.
+
+ This index has to be only built once for a file and is written into
+ the BL_proxy directory structure for later reuse in different blender files.
