  bwdif_vulkan: convert to storage images
  
  texture() uses bilinear scaling; imageLoad() accesses the image directly.
  The reason why texture() was used throughout Vulkan filters is that
  back when they were written, they were targetting old Intel hardware,
  which had a texel cache only for sampled images.
  
  These days, GPUs have a generic cache that doesn't care what source it
  gets populated with. Additionally, bypassing the sampling circuitry saves
  us some performance.
  
  Finally, all the old texture() code had an issue where unnormalized
  coordinates were used, but an offset of 0.5 was not added, hence each
  pixel ended up being interpolated. This fixes this.

  avfilter/libplacebo: use a transparent default fillcolor
  
  This will leave the background transparent when the target format
  contains an alpha channel, without affecting the behavior on formats
  without one.
