feat(RotateTool): Scale multiplier for rotate angle (#1322)
feat(RotateTool): Scale multiplier for rotate angle (#1322)

Removes horizontal/vertical strategy's usage of viewport scale to affect the amount of rotation,
causing inconsistent rotation amounts (and wild values on mobile devices). Applies user-configurable
scale and absolute distances in h/v strategies similar to default strategy.

BREAKING CHANGE: Horizontal/Vertical strategies no longer scale the rotation amount by the image
zoom level, but by a user-defined static value
