[Android] One-finger drag rotates model, when initiated on the model

[Solanaar]

Currently, you can only rotate the model, when you initiate the rotation off model (i.e. on the background). But, when using a pen, dragging on top of the model with your finger does nothing.

Suggestion:
To improve the UX, dragging on top of the model with one finger should initiate the same action as dragging over the background (default: rotate).
