Peek3D 1.2

Added

• Animation timeline: drag (or click) the bar to jump to any instant, for
  glTF and FBX. Playing resumes from where you left it. Keyboard: focus the
  bar and use ← →; VoiceOver: swipe up/down, the position is spoken in seconds.
• FBX skinning and blend shapes: skeletal meshes now deform with their
  animation instead of staying in the bind pose, and animated blend-shape
  weights play back.
• glTF files with Draco-compressed geometry (KHR_draco_mesh_compression)
  now open; a damaged Draco stream shows an error instead of crashing.
• KTX2/BasisU textures (KHR_texture_basisu) are covered by the test suite:
  they were already decoded by GLTFKit2 and now have fixtures that prove it.

Fixed

• A KHR_texture_basisu texture naming a missing image crashed the app
  instead of showing an error.
