v1.12.1

• Main
  • add optimized PF_R8 scaling & conversion
  • add overloads for MaterialPtr ManualObject
  • improve Singleton documentation
  • properly export RenderOperation
  • Texture - also unset TU_AUTOMIPMAP when mNumMipmaps == 0
  • update SSE2NEON to fix softwareVertexSkinning
  • use general softwareVertexSkinning implementation instead of NEON
  • Add missing nullptr_t constructor for SharedPtr
  • Do not replace existing entries in ResourceGroup index
  • use std::map::emplace instead of std::map::insert to simplify code
  • OgreETCCodec: KTX container: add support for a subset of ASTC textures
  • OgrePixelFormat: fix obvious typo in computing astc_slice_size()
• XMLConverter
  • do not attempt to create "" named materials
  • use Listener to keep material references for mesh2xml
• CMake
  • Android - fix installation of core resources
  • Android - port build to gradle
• SWIG: export VertexElementList and ignore some deprecated stuff
