The normals haven't fix yet, this commit is mainly preparing for the next coming commits about animation export.
The glTF text format abandoned for the binary format.
Add a crc64 hash check for history keeping to avoid repeated snapshot.
Besides, before, there is a logic error in the undo implementation, which recover the most recent snapshot from undo stack, so user need undo twice and at the second undo get the expected result. This incorrect behavior got fixed.
Many source file name and data type are prefixed by "skeleton" before, now all are refactored.
The class MeshResultContext represents the outcome of mesh generation before, now we have material, pose and animation, so we just rename it as Outcome.
Shortcuts implementation now use QShortcut instead of using the raw key event.
Besides, hold spacebar to temporarily enter drag mode also implemented in this commit, this is very useful in zoom mode.
Before we use a tricky way to share mouse event between model render widget and model edit widget, which forward the event from render widget to edit widget. This will cause some problem, such as the scroll bar of edit widget would not work when it covered by the render model.
Now the mouse event is totally disabled in the render widget, and when there is a need we forward it from edit widget.
Curve editor has been removed from this commit.
Instead of let user edit customized curve for motion, we provider presets. It's much more easy to add motion than before.
Now, we have our own automatic uv unwrapping library: simpleuv
thekla_atlas works good on good mesh, however, sometimes, it crashs and cann't handle bad cases very well.
Besides adding the PBR material manager, this commit hide some unnecessary features such as toggle wireframes and toggle normal smooth.
Add a regenerate button to indicate mesh is generating by showing a spiner, user can click this button to regenerate if the final result is not good.
Please note that, we generate the texture map by default compared to before we only generate texture map when user export glTF result. Current uvunwrap library cann't handle bad mesh very well, so it will crash on the wires model.
