Shotpad 1.0.6

Screenshots can now wear an outer border — a mat between the picture and
the background, led by a frosted-glass preset.

A translucent white band is what most "beautified" screenshots on the web are
wearing, and a flat colour never quite matches them. Measured across a real
one, the sheen is about 25% white along the top and left edges but only 14%
along the right and bottom: it fades across the diagonal, as though lit from
the top-left. That gradient is what makes it read as a pane of glass instead
of a coloured margin, so Glass is a fill mode rather than a colour, and it
works with any colour you point it at.

Added

• Outer border in the Image panel, sized as a share of the screenshot's
  short edge rather than in pixels — so it survives an export at any scale and
  looks the same on a phone-sized crop as on a 4K capture.
• Eight presets: Glass, two frosts, white, two smokes, black and paper.
  Picking one on a zero-width border opens it up so the choice is visible.
• The band is part of the plate, so it casts the shadow and tilts with it. The
  shadow's blur and offset stay keyed to the screenshot, and padding is
  measured from the outside of the band, so adding a border never silently
  restyles the shadow or eats into the padding.

Changed

• Border swatches preview over your current background instead of a
  transparency checkerboard, which only ever said "this colour has an alpha
  channel" — every translucent preset came out as the same grey lattice. On a
  pale background the white presets now correctly look nearly invisible,
  because that is what they will be.

Fixed

• The sidebar scroll bar was unusable in a small window. Shotpad draws its
  own window chrome, so it has to reimplement the resizable edges, and the
  outer 8px it claims for them swallowed the scroll bar's 6px handle whole:
  hovering it gave a resize cursor and dragging it resized the window instead
  of scrolling. Scroll bars and sliders now take the pointer first. Every
  corner still resizes.
