[vtkusers] BUG: vtkImageData::ComputeBounds() ... + solution

When the time comes to do the change, I've already got a vtkImagePlotActor class which has options

PixelRecentre(On/Off), this shifts the pixel points so that they lie in the centre of the pixel (and the uses bounds +/- 0.5 at each
edge).

IncludeEdgePixel(On/Off), this option effectively expands the size by one or not to take into account the +1 effect at the far edge

It is only working on 2D plots (maps and overlays etc) at the moment and uses other customized classes so I couldn't contribute it
as is, but in principle I may be able to help.
