Sujet - Avoyd 0.8.14 - Orthographic camera level of detail and shadow culling fixes, and improved World Properties window performance

This release fixes the following issues in the Voxel Editor:

• Level of detail system for orthographic views changed to use visible distance instead of distance to objects
• Shadow maps now correctly frustum culled when using an orthographic camera

We've also changed the World Properties window to improve performance by only calculating dimensions on window appearance, loading a world, or when manually refreshed. (Menu View > World Properties)

Avoyd Voxel Editor GPU real time render using an orthographic camera in version 0.8.13 (above) - The GPU rendered level of detail depends on the distance to the camera, which with an orthographic camera does not correspond to the size of an object, so voxels can appear blocky. In Avoyd 0.8.14 (below) - The level of detail is fixed: it now depends on the orthographic width so details are preserved depending on the setting 'LOD Change Distance' (in menu Graphics Quality).
