Mirror

[fsobolev]

A new "Mirror" setting that can be in one of 3 states:

• "Off"
• "Vertical", in this state the drawing area will be split in half vertically, the upper part will contain bars for left channel, the bottom part will contain bars for right channel (similar to cli-visualizer), or if channels are set to mono the bottom part will be an exact mirror of the upper part.
  
• "Horizontal", same as previous, but the drawing area will be split horizontally.

This setting will have no effect for the Circle drawing mode (planned for the same release).

@fsobolev Do you already have an idea of how this setting should be implemented? I was thinking of a simple Mirror setting in the preferences window, with a dropdown list. The list contains the options "Off", "Horizontal" and "Vertical".

We might also want to integrate this into #9 and create a keyboard shortcut for changing the mirror setting.

Yes, I was thinking exactly as you said. :)

I also like wavy, though it's similar to what has been suggested in #15 .

This is basically Bars mode mirrored, but with inverted coordinates. I think I can implement 2 more options for mirror then: Inverted Vertical and Inverted Horizontal.
