GLib guarantees libintl is always present, using proxy-libintl as last resort. There is no need to mock gettex API any more. This fix static build on Windows because G_INTL_STATIC_COMPILATION must be defined before including libintl.h, and glib does it for us as part as including glib.h.

The Smoke Codec --------------- This is a very simple compression algorithm I was toying with when doing a Java based player. Decoding a JPEG in Java has acceptable speed so this codec tries to exploit that feature. The algorithm first compares the last and the new image and finds all 16x16 blocks that have a squared difference bigger than a configurable threshold. Then all these blocks are compressed into an NxM JPEG. The quality of the JPEG is inversely proportional to the number of blocks, this way, the picture quality degrades with heavy motion scenes but the bitrate stays more or less constant. Decoding decompresses the JPEG and then updates the old picture with the new blocks. TODO: ---- - make format extensible - motion vectors - do some real bitrate control
