faster material preview generation
since Slate introduction, material preview is much slower, needs to be the same as it was with the old mat editor

All the Slate Editor needs is a decent thumbnail caching system that remembers materials between sessions/different files, it can't be that hard to come up with one

This must be because the old material map browser showed no previews, whereas the new Slate material map browser previews everything. Maybe if the preference was set to view as text only as opposed to text and image, it would be just as fast.
