• Undo after "Fit To Sqr" not properly restoring shell positions.

Fixes and new features included in uvlayout-pro-2.07.02f-fc6:

• S key on shell in box will now correctly pack the mirrored shell.

• Added a 'Lock All to Tile' checkbox in the Pack menu. This also affects the box normalize functions.
  Can also selectively tag shells with the '#' key if you only want some shells locked into their existing tile during packing.

• Click the "Fit To Sqr" button to normalize the contents of all tiles.

Fixes and new features included in uvlayout-pro-2.07.02d-fc6:

• R key - Some shells collapsing when flattened further. Now use R or Shift-R depending on how the internal UVs are to be handled.

• Space and RMB on the corner of the box to scale it around that corner.

• Click on one or more boxes and execute rotations and movement on the box from the transform menu.

• Click on one or more boxes and use Space LMB/MMB/RMB transforms on them.

• Click on a box and normalize it to the U & V (or to U or V).

• S key to mirror across the center vertical axis of whatever grid or box it currently occupies.
