gst/videoscale/: Add a 4-tap image scaler. Theoretically looks much prettier.
Original commit message from CVS: * gst/videoscale/Makefile.am: * gst/videoscale/gstvideoscale.c: * gst/videoscale/gstvideoscale.h: * gst/videoscale/vs_4tap.c: * gst/videoscale/vs_4tap.h: * gst/videoscale/vs_image.c: * gst/videoscale/vs_image.h: * gst/videoscale/vs_scanline.c: * gst/videoscale/vs_scanline.h: Add a 4-tap image scaler. Theoretically looks much prettier. The tap calculation could use some improvement.
