This set of changes enables conversions for singly-nested slices. Multiple nesting hierarchies are only partially supported at this point. Conversion is also significantly more deterministic, which makes it easier to convert single slices without needing to reconvert every slice or level that relies on it as well.
Changes:
- Added version of Instance::AddInstance() that takes in an alias to allow for deterministic aliases
- Added a "SliceConverterEditorEntityContextComponent" that's used to specifically disable entity activation on creation. The disabling is done this way vs adding a new public API, because the disable shouldn't be required in any normal case outside of this tool.
- Disabled more AWS gems for the SliceConverter, as they're unneeded and cause issues if they're around in the tool.
- Added a small null check to the Camera Controller.
- Added the actual support for slice instance conversion. This instantiates the entities, applies the data patches, turns them into a prefab instance, and generates a JSON patch out of the changes.
* Fix some FOV calculation viewport issues:
-Avoid calculating FOV if we've got an invalid viewport
-Don't override game mode FOV, let the active camera components manage it instead
* Fix viewport font positioning
This updates code in a few places to respect an API change/fix made to AtomFont - also switched the default value of m_virtual800x600ScreenSize to false as it's really behavior you want to opt into
* Don't activate CameraComponentController when in the Editor / not in game mode
This ensures the camera entity's transform gets correctly set if the RPI::View (or ViewportContext) is directly used instead of adjusting the entity transform, for e.g. camera controllers.
