+/*
+ * filter to tile a serie of image in a single, bigger, image
+ *
+ * The parameters are:
+ *
+ * xtile: number of tile on the x axis (5)
+ * ytile: number of tile on the y axis (5)
+ * xytile: when write the image, it can be different then xtile * ytile
+ * (for example you can write 8 * 7 tile, writing the file every
+ * 50 frame, to have one image every 2 seconds @ 25 fps ).
+ * start: pixel at the start (x/y), default 2
+ * delta: pixel between 2 tile, (x/y), default 4
+ *
+ * For example a valid command line is:
+ * ... -vf tile=10:5:-1:4:8 ...
+ * that make images of 10 * 5 tiles, with 4 pixel at the beginning and
+ * 8 pixel between tiles.
+ *
+ * The default command is:
+ * ... -vf tile=5:5:25:2:4
+ *
+ * If you omit a parameter or put a value less then 0, the default is used.
+ * ... -vf tile=10:5::-1:10
+ *
+ * You can also stop when you're ok
+ * ... -vf tile=10:5
+ * (and this is probably the option you will use more often ...)
+ *
+ * Probably is good to put the scale filter before the tile :-)
