Add a "Bounding Box" method to Pack Charts that packs the UV islands of a tile by their bounding boxes using MaxRects (Best Short Side Fit). * auv_pack_maxrects: packs movable charts around fixed ones. Charts that do not fit stay in place and are reported as unpacked, selecting the ones that still overlap another chart. * auv_pack_utils: option validation, rotation candidates, convex hull and minimum-area oriented bounding box, chart bounds and transforms, shared with other packers. * Options dialog: profile (Fast, Balanced, Quality, Max), gap and margin as percent of the tile side, rotation step, and normalize orientation (rotates each chart to its minimum-area oriented bounding box before packing), plus "Scale to fit" when every chart is movable. * Works on the charts of the current tile; with an empty selection all of them are packed, otherwise unselected charts are obstacles. Expose the internal Wings3D packing (rows/columns) as the "Legacy" method of Pack Charts, next to the new packing methods. * Menu: "Legacy (Rows/Columns)" with an options dialog. * Options dialog: gap and margin as percent of the tile side, saved in the preferences like the other methods. * pack_legacy/2 arranges all charts of the current tile inside the tile's unit square (uniform rescale) using auv_placement:place_areas/3. The selection is ignored. * Adding option to Bounding Box method.

Add a "Polygon" method to Pack Charts that packs UV islands by their outlines, so small islands can fill the holes of larger ones. * auv_pack_poly: bottom-left fill on a conservative occupancy grid, verified with an exact polygon test, followed by a short exact compaction. Profiles control grid size, rotation candidates and compaction rounds. Islands that do not fit stay in place. * auv_poly: polygon geometry (collision with gap, containment). * auv_pack_utils: code shared by both packers (options, rotation candidates, OBB, chart transforms, outline extraction, scale search). * auv_pack_maxrects: renamed from auv_packing; uses auv_pack_utils. * New options: Max profile, polygon order, "Scale to fit" for both methods (uniform scale, only when every chart is movable). * Added option to legacy mode handle selected islands without scale them.

A new Pack option was added to AutoUV window giving access to three packing
methods: "Legacy (Rows/Columns)", "Bounding Box" and "Polygon".
The Legacy (Rows/Columns) option is the native Wings3D's packing method that
was exposed with the addition of options to define Gap and Margin;
Two new methods was added:
islands of a tile by their bounding boxes using MaxRects (Best Short Side Fit).
small islands can fill the holes of larger ones.
NOTE:
Added three packing methods to AutoUV: Legacy (Rows/Columns), Bounding Box
and Polygon.
