v2.0.1 — Smooth & Padding Fixes

Fixed

• Duplicate smoothing: on_smooth_clicked was calling
  laplacian_smooth_grid twice in a row. Removed the duplicate call.
• Padding drift on re-edit: pad_left and pad_top could shrink below
  their physical values when re-applying the filter, desynchronising
  grid-json from the actual canvas. Now preserved with max().

v2.0.0 — NDE + Puppet Pins

First public release of the fork with Non-Destructive Editing and Puppet Pins.

Added

• Non-Destructive Editing (NDE) via GIMP 3.2 Gimp.DrawableFilter
• Puppet Pins mode with windowed Gaussian RBF
• Pin Radius slider and Clear Pins button
• NumPy-accelerated pin rebuild (10–30× faster)
• GMutex-protected mesh cache in the C GEGL operation
• Dynamic triangle subdivision in the Cairo preview
• Dirty-rectangle redraw for grid-vertex dragging
• Round-trip state persistence across re-edits

Fixed

• Mode-switch state persistence (pins no longer lost)
• Windowed Gaussian falloff (no phantom deformation)
• Coordinate-system round-tripping after layer expansion
• Missing radio-button connect for Puppet mode
• Gegl.Buffer GI signature errors
• Build script auto-detects gegl-op.h for distros with incomplete pkg-config

Requirements

• GIMP 3.2 or newer
• NumPy recommended for Puppet-mode performance
