feat(editor): -generate-nodebank-previews mode: png previews of the node bank models, or of the entries given with -entries, drawn offscreen and without a window by the full renderer: square, -resolution 1024 by default, the model in perspective from the front, side and above, fitted to the image less -margin pixels (64 by default) on white background, lit, with materials and with self shadows unless -no-shadows; saved in textures/previews/nodebank under the path of the model with the skin; software rendering of mesa when the graphics driver gives no gl 3.3 or with -software
