v1.3

Changes since previous release

• HDView now supports multiple image editing tools including: paintbrush, clone stamp, eraser, eyedropper
  • each tool can take over the top panel to provide options
    • e.g. paintbrush supports selecting radius, hardness, flow, angle, roundness, spacing and smoothness
  • GUI shows selected tool's overlay on the image (e.g. the circle/ellipse of the brush)
