Bug in ERMapper driver. One pixel shift in coordinates.

Description

ERMapper header reader shifts the corner coordinates with one pixel. Gdalinfo displays this bug, which appears also in transformed images.

These are the coordinates in ERMapper header:

CellInfo Begin
  Xdimension = 20
  Ydimension = 20
CellInfo End
RegistrationCoord Begin
  Eastings = 610360
  Northings = 261040
RegistrationCoord End
RegistrationCellX = 0.0
RegistrationCellY = 0.0

and this is what gdalinfo produces:

Origin = (610380.000000000000000,261020.000000000000000
Pixel Size = (20.000000000000000,-20.000000000000000)

This bug has been reported before, see #3056 and #2612. I believe this should not be too difficult to fix.
