support draco compression in GLBRuntime

[tuket]

I added a model with Draco compression in the Azure shared folder, if you want to try it out.

Works as a charm in HoloLens, but I get some crashes when trying to open a model using a Meta Quest 2 device :(. Original duck model can be loaded without problem, but draco-compressed duck only loads 1 of each 3 attemps. Maybe some kind of race condition?

Need to check it with more draco compressed models to see if this is a common problem or not.

Just updated to latest Draco bindings library, and it looks like execution in both HoloLens and Quest is broken now, throwing following error:

It makes sense that it crashes in HoloLens because I have removed the UAP .dll.
I was told that UAP is deprecated and it's not going to be supported by Microsoft any more, so I decided to drop it since it was causing problem with VS targets.

However, I didn't remove the .dll for Android, so it's weird that it doesn't work in Quest. I suspect what might be the issue, I will take a look.

For June release we will still support UAP in Evergine, so we need that DLL back. For September release, it's true that this will no longer supported, and you could get rid of library for that platform.

I made a fix for this in EvergineTeam/NativeLibraryLoader#2.
However, I can't test it because I don't have an Android device.

Let's wait until that PR is merged :)

The EvergineTeam/NativeLibraryLoader#2 has been merged

I have updated XRV to reference to the newest Draco.NET which now uses the fixed NativeLibraryLoader.
It should work now in Android, although I can't test it because I don't have any Android device to test it.
Can anyone test it for me? Thanks!

Thanks for trying to update this, but you should merge changes from develop branch first. As you may see, we are no longer using Model Viewer module importers, they have been replaced by Evergine.RuntimeLoders for both STL and GLB :-/.

Does that mean that the RuntimeLoaders are now part of Evergine? The PR should be now made to the Evergine repo instead?

Yeah, if you need to change how current runtime loader works (for example adding that cache dictionary) you should do it in Core repository. Take a look to that code first, I think it already includes changes you made on GLBRuntime class. Maybe it's enough with merging current develop branch and check that native DLLs are properly loaded via Evergine.Bindings.Draco package.
