TextureProjection Op - More projection types

[franckaubry]

When working with deformed geometry in Cables.gl, I have seen a need to have access to more texture projection types.
I hope that there will one day be possible to select among these basic ones as well:

• Spherical
• Cylindrical
• Cubic

Another thing that would be helpful in some instances, is a simple widget type that gives a visual representation of the direction/rotation of the projection.
