• Removed

Other improvements

• Third parties : New Version LZMA libraries updated to 26.00
• Third parties : New Version zlib libraries updated to 1.3.2
• Third parties : New Version Freetype libraries updated to 2.14.3
• Dtk_LayerInfosSet
  • Dtk_LayerInfosSet and Dtk_LayerInfosSet::Layer now hold all information relative to layers, such as identifier, name, flags, and father identifier in case of tree hierarchy.
  • Dtk_LayerInfosSet::Layer flags indicate if a layer is selectable and/or visible, this information should not be provided by Dtk_Component anymore. By default, a newly created layer is visible and selectable.
  • Dtk_LayerInfosSet now uses current layer naming (see Dtk_LayerInfosSet::GetCurrentLayer) instead of default, which was confusing. This information should no longer be provided by Dtk_Component.
