- initialize slice map from subpicture map when single_slice_per_subpic_flag is enabled
- encoder support for inferring slice map from subpicture map
- improve software manual
Notes:
- This fixes an incomplete implementation of JVET-P1024, which was implemented mostly syntax-only due to missing subpicture parameters.
- I generally prefer fixing bugs separately. But the three referred bugs were just different aspects of a missing initialization process. Fixing a single aspect would still end up in a wrong initialization, so they were grouped together.
- I suggest reviewing for changes with "white space change" hidden setting (see gear symbol in diff view) since larger sections of code have been moved into a "else" condition and also formatting for a different "else" condition was fixed.
