Summary	0004365: Transforms module sliders do not recall rotation information and rotation by fraction of degree is not possible
Description	Transforms module sliders do not recall rotation information and rotation by fraction of degree is not possible. If a transform is saved and then recalled inside the Transforms module, the rotation information appears in the Transform Matrix but not on the sliders/text boxes below that. It is important to increase the precision of the rotation+translation information to allow for exact replication of our experimental simulation conditions.
Steps To Reproduce	Create 2 transforms Switch between them and see if the information is recalled Also, save them in a bundle and re-load. All the information should re-appear, but currently does not. Also, it's not possible to enter rotation by fraction of a degree, and this is needed.

lassoan 2017-06-14 12:34 developer ~0014831	Fixed in r26090. Now it is possible to enter fraction of degrees. Default spinbox step size is 0.1. Sliders are not set based on 3x3 orientation matrix because there is no one-to-one mapping between orientation matrix and rotation sliders that work for all orientations (gimbal lock problem).
