VDB orientation fix

Dear developers, please consider adding VDB orientation mode option. By default it is rotated -90 degrees. Adding this option would remove the necessity to rotate the mesh manually every time a VDB file is imported.

Yes, this would be awesome. :) Also it would be nice if the VDB was scaled to fit inside the domain. Now the VDB can come in many times larger than the domain and you have to scale it down a lot.

When the VDB is generated in Blender itself, the orientation is correct. Each software able to generate simulations is using its own coordinate system, so transforming the item in Blender may be needed.

When you import a VDB there's no "domain" concept. You're just using the item transformation to control size, position and rotation.
VDBs can have different size/scale according to the software used to generated them. If you generated the VDB for Blender you'll get the same exact scale and rotation.

What we need is a way to visualize the VDB in OpenGL.
