* Font loading (hidden under a .png for now). Simple experiments with rendering text
* Added some text rendering tests. WIP on billboarding
* Added tests using troika-text-three library which uses sdf font textures instead of generating text geometry
* WIP on supporting speckle text objects
* Some more work on speckle text object integration. Worked on text materials, text batch and text object. We're now rendering basic text
* We're now rendering the text for various dimension types. Changed text to use display style first, since that's the one that contains it's color.
* Implemented text selection. Text can now be selected and works the same way every other speckle objects works when selecting
* Implemented the rest of the filtering features for text.
* Batch building can now be async. Building text batches needs to be async because that's how the troika libary works. Fixed an issue with the section box not clippin text properly
* Removed dummy text geometry data from it's RenderData. Enabled render views with metadata to count as valid. getRenderableRenderViews now returns nodes with metadata as well. Text now supports proper unit conversion. Text now is being displayed correctly(-ish) when inside blocks. Autocad text is now being displayed
* 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.
* WIP on naive diffing
* WIP on animating modified objects after diff
* Some more work on this
* Default building
* Removed and added now get opacity transitions as well
* Updated starting model
* Implemented two 'subpasses' in side the color pass, where opaque and transparent draw groups are rendered individually. Disabled double side depth rendering when visual diffing, to avoid AO generated by backfaces, visible through transparent diffed objects. Removed previous hacks
* Finished with cleaning up diff-ing related viewer functionality.
* Implemented UserMaterialState into filtering manager, as a 'sticky' filter which always gets applied before any other filters, until removed. Visual diff-ing and undiff-ing now go through the filtering manager so other filters can be stacked on top of it
* diff API function now checks to see if the diffing streams exist, if not, it loads them, computes the diff and applies the visual diff all in one call. Added undiff in the API which removes all the diff related sticky filters. Added setDiffTime in the API. DiffResult now holds modifiedOld and modifiedNew speckle objects in the same member as 2 item sequential arrays
* There was an unreported git conflict in one of the shaders. Fixed that
* Fixed an issue with HDRIs not generating proper PMREMs over multiple viewer instances
* WIP on makign the world tree multiple instanced
* The WorldTree is no longer static. Each viewer has it's own instance and it hands it over to whoever needs it.
* Fixed an issue with filtering and the new non-static tree. Also removed the 'root' key from the NodeData structure since it's not needed
* Added an guard when building batches for situations where all render views have invalid geometries. This generally means there is somethign wrong with the stream itself
* multi-viewer css fixes

* The ObjectLoader and ViewerObjectsLoaders are disposed upon loading complete.
* Added viewer parameter for keeping or discarding original geometry data. Defaults to discarding it. WIP on mesh and point cloud implementation for actual discarding it
* Geometry data from raw nodes is now disposed after building their reder views
* Removed raw geometry data from points and lines
* Removed the float64 array which was persisted pointlessly by the section plane outlines feature. Also fixed a bug for this feature regarding resizing the point buffer and RTE
* Implemented BVHs in local space, relative to world origin. This cuts down on it's redundant memory footprint by half
* Implemented SpeckleMeshBVH which completely hides the RTE-related transformations that we're making to reduce memory footprint.
* Added some clarifications to the SpeckleMeshBVH class
* Implemented async walk for the world tree. Implemented asyn render tree building and async batch building. Implemented progressive loading
* WIP tree walk async that actually works using a generator
* Async walking now properly works and can be interrupted
* Properly working async walk
* Added loadObjectAsync function in the API which should be used if stream loading needs to be cancelled and for 'progressive' loading. Added a priority argument to the loadObjectAsync and to walkAsync functions which makes the async-iness so to speak configurable.
* Refactored the sync and async subtree batch building to remove duplicate code. Changed some logs for better clarity
* Fixed an issue with point clouds and material creation
* Added a verbose flag in the viewer params. Default is false and it's equivalent to the ERROR level
* Piggybacked the original pointer event into the SelectionEvent
