Fixed errors on drawing bhkPackedNiTriStripsShape

 * Implemented experimental glTF export and import for Skyrim: Special Edition, Fallout 4 and Fallout 76. See [README\_GLTF.md](https://github.com/fo76utils/nifskope/blob/develop/README_GLTF.md) for details, and known limitations and issues.
 * Updating bounds has been implemented for skinned BSTriShape meshes, and 'Update All Bounds' is now applicable to Skyrim Special Edition NIFs.
 * The viewport is now enabled by default on opening a new window, and not only after loading a NIF. This allows models imported to a new window to be visible, but may increase startup time, because resources need to be initialized for the default game (the default NIF version can be configured in the general settings).
+* Implemented triangle selection on triangle strips, shift-clicking selects the last point of the triangle.
+* Added keyboard controls for setting the light direction: F, L, T, Up, Down, Left and Right control the light source instead of the camera if Shift is held down.
 * Fixed incorrect sorting of link rows.
+* Fixed errors on drawing bhkPackedNiTriStripsShape.
 * Fixed the light direction being reset on changes to the render settings.
 * Fixed loading Fallout 76 and Starfield cube maps with legacy DDS header.
 * Minor optimizations: faster cube map filtering, and use of SIMD data types in 'noavx' GCC and Clang builds.
