Now you can set most anything you'd want from the commandline:
```
Usage: fbmirror.py [OPTIONS]
Options:
--x-offset INTEGER The x offset of top left corner of the
region to mirror
--y-offset INTEGER The y offset of top left corner of the
region to mirror
--num-address-lines INTEGER The number of address lines used by the
panels
--num-planes INTEGER The number of bit planes (color depth. Lower
values can improve refresh rate in frames
per second
--orientation [Normal|R180|CCW|CW]
The overall orientation (rotation) of the
panels
--pinout [AdafruitMatrixBonnet|AdafruitMatrixBonnetBGR|AdafruitMatrixHat|AdafruitMatrixHatBGR]
The details of the electrical connection to
the panels
--colorspace [RGB888Packed|RGB888|RGB565]
The memory organization of the framebuffer
--serpentine / --no-serpentine The organization of multiple panels
--height INTEGER The panel height in pixels
--width INTEGER The panel width in pixels
--help Show this message and exit.
```
It might would be good to apply this generally across the examples.
