This fixes https://github.com/godotengine/godot/issues/20377 , where blend shape scales the mesh if the mesh is also skinned.
The issue was that the blend shape was trying to blend using BLEND_SHAPE_MODE_RELATIVE (directly adding everything in morph shape as displacement), while bone weights were copied in the morph shape, which resulted in 2x bone weights causing mesh to become bigger when blended.
Setting the blend mode to BLEND_SHAPE_MODE_NORMALIZED while guaranteeing the data is correct fixes the issue (previously treating gltf2's morph displacement data as blend target data). Ideally we still want to use BLEND_SHAPE_MODE_RELATIVE since it may need much less data, but that seems to require a larger refactor?
It's now smart and keeps track of every entity in the doc files. Now it can pick up on broken references and such inside the doc files.
Eventually we'll be able to run it on Travis and check for errors automatically.
General file cleanup.
References to elements of classes now have a prefix for their type. class_Control_minimum_size_changed becomes class_Control_method_minimum_size_changed, or signal_, because the reason I did this was to fix reference conflicts.
You can also reference constants now with BBCode.
Also made it use argparse, adding an --output and a --dry-run argument.
I did not fix all the errors it's reporting in the documentation files, there's about 150+ of them but that's outside of the scope of this commit.
Man this file even had some semicolons in it.
I cleaned up the entire file, while it's still pretty ugly it's much better now.
I also added type checks so it passes mypy --strict.
make_type now throws a warning on unresolved type references, which there are a bunch of. I'm not responsible for fixing those though.
Also some more hardening against crashes. For example XML tags without content won't cause crashes now.
Functionality has not been modified as far as I can tell.
Update Makefile for Python 3
Fix ordering issues related to enums & constants
Retrieved working implementation from 2.1 branch and adapted to
existing export preset system.
Added Script tab in export preset to export script as raw text,
compiled, or encrypted (same as in 2.1). The script encryption key is
visually validated. The script export mode and the key is saved per
per preset in `export_presets.cfg`, so it makes sense to ignore this
file in version control system.
Each custom exporting procedure can retrieve an export preset set
during project exporting. Refactored project export dialog a bit to
allow easier code comprehension.
