[Motmot] fview plugin drawing with ROI

[John Bender]

I've got an fview plugin that returns a few points to be drawn on the
image. When I use a hardware region of interest in the fview camera
settings, the points are drawn on the fview window relative to the
bottom of the window, not the bottom of my ROI. (E.g., I set "height"
to 305 and "bottom" to 70, my plugin wants to draw a point at (50,50)
relative to the ROI, fview should draw that point at (50,120) but
actually draws it at (50,50).) Should I be adding the ROI offset to
the points before returning them, or is this a bug in fview?
