I thought one solution was to sub-class FigureCanvas, with extra 
buttons, but from what I understand, it is not that easy to do this at 
the platform independant level.

  But maybe adding arguments to the function call, for exemple imshow(x, 
set_contrast=True, linescan=True) plus keyboard toggles is enough?

What do you mean by mask editor? Something like a slider to adjust a 
threshold with a superimposed mask?
