emersion/libliftoff v0.2.0

on Freedesktop GitLab

• All functions which can fail now return zero on success, and a negative error
  number on failure. This allows callers to get more information about failures.
  
• liftoff_output_needs_composition and liftoff_layer_needs_composition have been
  introduced.
  
• libliftoff has migrated to gitlab.freedesktop.org.
