Subject: [PATCH] gst/speexresample/gstspeexresample.c: Add a "filter-length"
 property that maps to the quality values for compatibilty...

Original commit message from CVS:
* gst/speexresample/gstspeexresample.c:
(gst_speex_resample_class_init), (gst_speex_resample_set_property),
(gst_speex_resample_get_property):
Add a "filter-length" property that maps to the quality values
for compatibilty with audioresample.
