Title:
  nona-gpu result width is padded to a multiple of 8

Status in Hugin - Panorama Tools GUI:
  Fix Released

Bug description:
  initial tests by Thomas Modes show that the result of nona -g
  sometimes differ from the expected result by a few pixels on the
  horizontal. This is likely caused by the padding to a multiple of 8
  for faster GPU transfer. We need to identify the padding pixels and
  remove them from the end result. It would be a bug if an equirect of
  398x199 would return as 400x199.

  this is critical for the upcoming 2009.2 release.
