Emma Broman c165098cdc Point cloud rewrite (RIP RenderableBillboardsCloud) (#2932) 
* Start refactoring billboardscloud renderable

* Remove extra unit computation in geometry shader

* More refactor and fix size parameter not working without colormap (it never did)

* Remove redundant bool in shader

* Divide settings into property owners

* Refactor colormap

* More refactoring (utilize properties for visiblity)

* Remove redundant extra data structures for options

* Move data logic to the colormap settings structure

* Remove confusing correction size properties

* Separate polygon cloud into its own renderable

* Clean up some unused code

* Update some property descriptions

* Split some more code out into functions

* Remove odd and unused "linear filtering"

Should be reimplemented ina better way in a general color map overhaul

* Start refactoring some more properties

* Make color optional and remove redundant color assignments in assets

* Refactor color-parameter input and make range mapping work correctly

* Code cleanup (unused code and fix data types)

* Rename ScaleFactor to ScaleExponent

* Add a scale factor as well, as they're easier to use, and clarify documentation

* Fix faultily renamed scale factors

* Remove confusing multiplication for scale exponent

* Fix problem with points not appearing when _drawElements was set to true

* Move all colormapsettings into its own table in the asset files

* Move scaling/sizing into its own table as well

* Group sizing properties and remove min pixel size limit (was always zero)

* Add some docs and rename a parameter to avoid repetition

* Remove IsExact colormap and add an option to hide outliers

OBS! Still need to update the actual cmap files

* Add property to disable size mapping

* Increase pixel size of polyon texture - reduces jagged edges

* Remove unused points class

* Rename files and billboard class, to make it clearer that it is a point cloud

* Move size mapping into size settings

* Move color map properties out into its own component

* Move color map related computations into the new component

* Add outlier colors, to cover some specific color mapping issues

* Automatically fill parameter options if no colormap parameters were defined

* Move all color-related parameters to under one property owner

* Inlcude changes from matrix maintenance

* Add a checkbox to disable additive blending

* Remove a unused variable in shader

* DO color maping on the graphics card instead of CPU, using a texture

* WIP remove old "Outliers" and start introducing concept of no data colors instead

* Move speck loader to core and divide into a general data loader and a speck specific loader (In preparation for adding CSV support)

* More labelscomponent to core

* Fix a faulty header

* Handle NaN values

* Rename color map component property owner

It's not just the color map, but the settings for the entire mapping

* Hide point with nan value is show missing data is not selected

* Fix labels component documentation after move

* Add option to not provide any texture, and use a sphere generated form the shader

* Don't crash when loading unsupported data formats :)

* Add some TODO comments that should be addressed before merge

* Move renderables from DU module to base, and do some header cleanup

* Move colormapping component to core ad rename it to make it clear that it is not the color map itself

* Add above, below and nan color values to cmap loading

* Remove missing Data value specs in asset (and use belowRange in cmap instead)

* Make warning about wrong color number more verbose

* Add TODO comment about colormap, and actually used color in prev version, to localdwarfs

* WIP: Load CSV files

* Update some property visbility

* Check if chosen parameter options actually exist

* Fix fault column check

* Update example asset to cover more different cases

* Use new asset.resource loading

* Update asset versions (major update)

* Add parent documentation for RenderablePolygonCloud

* Add point cloud example with size scaling and add TODO comment

* Add example with textured points

* Don't blend textured points

* Fix problem with shaders being confused about texture units

* Bring back deepsky points color

* Start implementing more sophisticated datamapping for point data files

* Allow reading datamapping from input dictionary

* Load dataset in constructor instead

Solves problem with color map columns not loading for big datasets when loaded the first time

* Fix crash from reading column value that is interpreted as inf

* Inlcude information about data mapping when caching dataset

Updating the parameters now leads to an updated caching of the data file

* Adapt to tolower update

* Add option to specify columns to exclude in load (for CSV files)

* Start updating some docs

* Add a readonly property that shows the number of data points

* Rename example asset to shorter name

* Add option for not using cache when loading dataset

* Fix some errors in example asset

* Set scaleExponent from max position if not specified

That way the points are always visible, even when no exponent is given

* Restructure and add explanations in example asset

* Add option to not cache labels component data file

* Add example file with labels and units

* Compute fade distances in model coordinates instead of world space (issue #1746)

* Add possiblity to invert fading and add exmaple asset

* Make a separate propertyowner for fading settings

* Update docs

* Add example asset with custom data mapping

* Address some of my own review comments

* Read provided Parameter from asset

* Read ValueRange from asset

* Add example asset for more advanced color mapping settings

* Allow using the same column for two position coordinate axes

* Update src/rendering/colormappingcomponent.cpp

Co-authored-by: Alexander Bock <alexander.bock@liu.se>

* Update src/data/datamapping.cpp

* Use helper function for tolowercase

* Simplify some std::optional handling, and fix broken assignment from code review fix

* Update data file versions to get updated cmap files

* Include a progress bar to show progress of CSV data loading

* Update csv data-to-float parsing for clang

* Add a description about why `openspace.absPath` is used in the file instead of `asset.resource`

* Apply suggestions from code review

* Apply suggestions from code review

* Add some missing info in documentation

* Place size-related property descriptions next to each other

* Remove the explicitly set renderbin

* Fix overly complicated description

* Fix polygon texture not being used

* Add polygon cloud example

* only bind texture and activate texture unit when required

* Rename alpha to opacity in shader

* Fix value range not loading, and make first parameter in list the default

* Rename Pixel Size property

* Use base 10 for scale exponent instead of base e

* Update src/data/datamapping.cpp

* Update modules/base/shaders/billboardpoint_gs.glsl

* Remove some redundant asset settings (Home label)

* Review comments

* Add TODO comment for localdwarfs asset (Speck file reading problems)

* Oops, forgot part of the comment

* Apply suggestions from code review

Co-authored-by: Alexander Bock <alexander.bock@liu.se>

* More code review fixes

* Fix faulty isReady check when labels are included

* Apply suggestions from code review
