* WIP on measurements. Got some basic functionalities going
* New update for measurements. We're no showing multiple lines towards the measurement endpoint for better reference. Added dotted lines. Added text. Added measurement end and start points. Added the possibility to add multiple measurements.
* When double clicking, Input will not ignore the second click and will not send a click event. It will send the first click event, then a double click event. Implemented auto perpendicular measurement by using double click
* Added the option to have fixed sized measurement gizmos. As in, the are the same size regardless of the camera zoom. Implemented gizmo styles which lets us control and change at runtime the way the gizmos look. Currently they're only programatic, but I'll add controls for them in the sandbox next
* Implemented measurement management. Added picking, cancelling, removing and highlighting of measurements. Measurements are all now on their special ObjectLayer
* Added frame lock, so mouse events do not trigger intersection tests more than once per frame for the measurements. Added opacity options in the measurement gizmos. Made the end gizmo line transparent by default. Added preprocessor macro in the line shader which enables opacity as a uniform as opposed to attribute only like we had it before
* Point is now fixed size when style imposes it
* WIP on text aligning with the line. Still needs some things to be clarified since it can get complicated. Fixed some color issues. Added a maximum constraint to the screen space gizmo sizes. It's empirical, but seems to be workign decently for the all the various stream sizes I've trid
* Measurement gizmo now flashes red a few times if requrested to auto-lazer and no intersection was found
* Added unit conversion to measurment text, unit display and precision
* Implemented proper billboarding (fixed size and non fixed size) in the text and basic vertex programs as well as support for them in the text and basic speckle materials. Overhauled how the measurements look based on the forge reference
* Split measurements by type and added an abstract superclass. Point to point measurement has it's own implementation now
* Implemented screen space snapping for point to point measurements. Text background now gets dyanamically resized when needed
* End point gizmo is now only shown when required
* Added clamp guard to acos since dot can return outside of [-1,1] due to fp precision issues. Fixed an issue where existing measurements could be selected in the process of creating another measurement
* Added function for adding measurements programatically. Currently only start and end point make sense as measuremetn data
* Added an 100nm offset from the original point along the surface normal for auto-lazer function because sometimes it would intersect itself and report incorrect length
* Separated all measurement related rendering into a separate 'Overlay' pass. We now have better control over the rendering order of the individal elements of the measurement gizmos. This fixed the issue of having the measurement line overlap the end points
* Billboarded shaders now also work correctly with section planes
* Measurement tool no longer considers surfaces clipped by the section box
* Implemented correct raycasting for billboarded and fixed sized bibboarded objects, like the measurement's text
* Implemented zooming in to measurements when double clicking
* Big update to measurements which addresses most if not all requirements regarding UX/UI, API, and generaly functionalities. Additionally, a fix or an ancient issue in Units where kilometers were incorrectly calculated, and added automatically resolution updates to the SpeckleLineMaterial
* Added dpr factor into billboard size calculations. Fixed an issue with the round rect geometry generation function which would fail on macos. Added the billboard text background size into the text's style so it's configurable
* Text can now be updated for perpendicular measurements also when in it's complete state
* Fixed an exception which was thorwn when double clicking on another measurement while measuring
* When changing the measurement type while the measurement is still in it's dangling start state, the measurement gets cancelled and a new one with the new type gets started. If the measurement is in it's dangling end state, then it does not. This is now forge viewer does it
* Implemented screen space surface normal indicator line
* Measurements now work on visible and non-ghosted objects. Removed the surface normal indicator from the point to point measurement
* Fixed an issue with orthogrtaphic camera and NDC normal computation. Implemented fixed sized gizmo disc for orthographic camera
* Fixed an issue where the pipeline would not get properly reset after zooming in orthographic mode
* Fixed some regressions with the pre-existing application measurements functionalit and text. Fixed an issue where auto-lazer measurements were not vertically centered.
* Replaced the full blown copy method from SpeckleMesh's cached material with a faster version which *should* work just the sam
* Added optional copying of cached materials defaulting to false
* Implemented the option to insert draw ranges in batches. This is how selecting objects now works in order to avoid re-applying existing filters pointlessly. The onyl downside is that this introduces extra draw calls and overdraw, but it does not interfere with the existing draw range setting systems. We do make an attempy to minimize extra draw call count which works for most scenarios. With this change, we've removed selecting/unselecting objects from the generic setFilters approach in FilteringManager
* Apply any pre-existing selection filter after applying the rest of the filters
* Improved 'setNumericColorFilter' and 'setStringColorFilter' function performance by 10x. The culprit was calling 'indexOf' in the tree walk callback which apparently is very slow even for arrays with only a few thousand elements. By using direct indexing we eliminated the ridiculous overhead
* Performance increase of about 20x to isolating, hiding, unisolating and unhiding. Still WIP, the UI got messed up a bit
* Correct length of visibility ids
* Fixed an issue with un-isolating and un-hiding
* Did the same thing for highlight as I did for selection, where we take it out of the setFilters flow and apply direct filters on the rvs
* Removed timings
* Small fix for color filters
* Implemented inserting and removing draw ranges from the line batch
* Implemented draw range insertion and removel for the point batch
* Implemented draw range insertion and removel for TextBatch. Fixed an issue with inserting draw ranges in the batcher
* Fixed diffing colours which got screwed during this PR. Additionally made an even faster version for copying materials which has virtually no overhead
