  avutil/frame: check return value for cropping offsets
  
  This function can return AVERROR_BUG in theory if something
  went wrong, but so can the caller, so we should propagate that
  error message upward in that case.

  vulkan: enable using .elems field for buffer content definitions
  
  This avoids needing to snprintf when the buffer only contains an array of a struct,
  while letting the validation layers detect errors more reliably.

  ffv1enc_vulkan: support default range coder tables
  
  This adds support for default range coder tables, rather than
  only custom ones. Its two lines, as the same code can be used
  for both thanks to ffv1enc.c setting f->state_transition properly.

  avcodec/ffv1enc: Fix RCT for GBR colorspace
  
  It performs better when its less buggy
  
  Compression changes for rgb_scanline_half_piz_dw_t08 (using float16 with remaping) from
  56086 byte to 34371
  (with a single slice its 28122 byte)
  
  prior remap it was 188186 bytes
  
  ACES_OT_VWG_SampleFrames/ACES_OT_VWG_SampleFrames improves too but only by a fraction of a percent

  avcodec/ffv1: Store remap flag per slice
  
  This allows switching it on conditionally and also for non float,
  it may improve compression for RGB data that was paletted
  or other synthetic images
