diff Framework/Viewport/WebGLViewportsRegistry.cpp @ 1331:ab81ee8fce1f broker
- Viewport is not passed and stored as a shared_ptr instead
of raw reference.
- ViewportController can now be injected with an undo
stack (not a ctor param anymore, as a preparation for the
move of the undo stack to an interactor)
- Added (temp) flag to disable emscripten events registration
in the WebAssemblyViewport (because legacy client code
deals with them directly)
- Added emscripten_clear_timeout in ~WebGLViewportsRegistry
- Removed GenericToolbox::HoldingRef whose responsibility is
better served with proper callback un-registration.
