Rasterize off by one pixel

I'm trying to make a 100x100 pixel image using Rasterize, as follows,
where n=100

Rasterize[
  Graphics[Rectangle[{0,0}, {1,1}],
                PlotRange->{{0,2},{0,2}}],
  "Image",
   RasterSize->{n,n}
]

when I check the resulting image using ImageDimensions, the size is
100x101. If I say size {n,n/2}, then the image is 100x51 instead of
100x50.

Any ideas what causes this and how to fix it? Thanks.
