This function solves the problem of having to switch between camera and non-camera views.
When viewing from the perspective of mat, and having the view center ofs, this calculates a distance from ofs to the matrix mat. Using fallback_dist when the distance would be too small.
mat | A matrix use for the view-point (typically the camera objects matrix). |
ofs | Orbit center (negated), matching RegionView3D.ofs, which is typically passed in. |
fallback_dist | The distance to use if the object is too near or in front of ofs. |

Create a MEMFILE undo-step for locked camera movement when transforming the view. Edit and texture paint mode don't use MEMFILE undo so undo push is skipped for them. NDOF and track-pad navigation would create an undo step on every gesture and we may end up with unnecessary undo steps so undo push for them is not supported for now. Also operators that uses smooth view for navigation are excluded too, but they can be supported, see: D15345.
