Original commit message from CVS:
* gst/videoscale/vs_scanline.c:
(vs_scanline_resample_nearest_RGBA):
Revert optimization in videoscale. It should go in liboil and have
an appropriate liboil function.

ced6e8445a gst/videoscale/vs_scanline.c: C-level optimization of the RGBA nearest neighbour function.
Original commit message from CVS:
Reviewed by Edward Hervey  <edward@fluendo.com>
* gst/videoscale/vs_scanline.c: (vs_scanline_resample_nearest_RGBA):
C-level optimization of the RGBA nearest neighbour function.
Eventually this might end up in liboil with vectorized versions.
