v0.3.8

Runtime changes

• Read pma from AtlasPage for Spine version 4.0 and later.
  • For these versions, manual toggling of PMA is not permitted. But there would not be a file faking its property.
• Delete depth-buffer feature.
  • Depth-buffer is unreliable when alpha channel is crucial.
• A few trivial code clean-up.

Viewer changes

• Add filtering in file-select-dialogue.
  • For altas, *.atlas and .atlas.txt are condidates. For skeleton, *.skel, *.bin, *.json and *.txt are candidates.
  • To display other extensions, select All files(*) on file-select-dialogue.
