15 This filter requires two passes. The first pass performs analysis and stores
16 the result in the vectors property. The second pass applies the vectors to
18 To use with melt, use 'melt ... -consumer xml:output.mlt all=1' for the
19 first pass. For the second pass, use output.mlt as the input.
26 A set of X/Y coordinates by which to adjust the image.
27 When this is not supplied, the filter computes the vectors and stores
28 them in this property when the last frame has been processed.
