- fix broken sculpt material that went to white in many cases, replace with diffuse shading and rim light in Emissive channel / unlit texture
- add image-based sculpt materials provided by techart, expose custom variant that allows user-defined shader image
- make flat shading optional in view settings, for relevant shaders
- reorganize properties and update tooltips to be more informative
- fix broken Falloff support and expose in property set, display in brush highlight. Make this separately exposable in BaseBrush property set since we don't need Strength.
- add viewpoint-based Sculpt and Plane brush modes
- fix brush preview location when in hover, was not respecting target surface setting
