* Fixed an issue with curves doubling up on geometry and also not being selectable after the last filtering changes. Added the options to make lines transparent. Added lines to diffing
* Points now are diff-able and support proper visual diff-ing. Visual diff filters are now chosen internally by the Differ. Fixed an issue with LineBatch and transparency
* Implemented PLAIN visual diff mode, where all objects keep their original materil, but opacity is manipulated via the diff time. Added API member function to switch between the PLAIN and COLORED visual diff modes
* Diffing fixes for instances and blocks. Things seem to be working fine, but there are some caveats. Additionally, some older issues were fixed and diffing now works better on all the rest of the streams
* Fixed the diffing issues with revit instances and hosted elements and nesting, etc. SetUserMaterial now accepts an optional list of rvs to apply the filter to, instead of figuring out the rvs itself.
