rotate native models

[thperez1972]

There seems to be an inconsistency between how to rotate custom models and native models. For custom models, there's a rotate option in the model data. The native models can be moved around in any direction but xlights doesn't see the change as the default. The render style in layer settings has to be changed to per preview for every effect on the native model. Unless there's a technical reason why native models can't be rotated, the ability to rotate them, even without the ability to modify the model data, would help dealing with native and custom models a little more consistent.
