It seemed to me like a bug, but may as well be a feature request
Please check the PG.
If I use AssetsManager to load a texture when using NullEngine, I expect that
onTaskSuccess callback would return
task object, that would contain texture instance in
task.texture, just the same as when using normal Engine.
Unfortunately, in that case
task.texture is undefined.
Would it make sense for NullEngine to call
onLoad callback with some artificial asynchronicity?
