#103 Rotate and Mirror view

[Pela R. Donable]

Individual layers can be moved, but and addition of viewing board Mirrored, or/and Rotated would be helpful.

[Berni Joss]

I use the following cli options to display the board mirrored and rotated:
-r, --rotate=<degree> Set initial orientation for all layers.
-m, --mirror=<axis> Set initial mirroring axis (X or Y).
Did you try them?</axis></degree>

For example, to see the board up-side-down (flipped along y-axis) and rotated 90 deg:
$ gerbv -my -r90 -p Gerber/gerbv.gvp &
