- Imported animations now have the auto_play and loop flags set to false by default - Implemented Pre-Rotation, Post-Rotation, Scale Offset, Rotate Offset, Scale Pivot, and Rotate Pivot transform attributes. - Reduced use of euler angles, replacing them with Quaternions where possible - Fixed bug with incorrect Y rotation in KRMat4::rotate - Material / GL Context changes have been optimized to reduce redundant glUniform calls - New KRMesh format implemented, with support for importing BindPose matrices - Fixed bug that caused a duplicate "default_camera" node to be added rather than picking up an existing "default_camera" node imported from FBX. This enables animations to drive the camera correctly. - Implemented KRVector3::Scale - Implemented KRVector3::KRVector3(double *v);
