Spatially warp an MSS image to match the spatial properties of a reference image

1 2	msswarp_old(reffile, fixfile, window = 275, search = 27, sample = 1000, refstart = c(0, 0), fixstart = c(0, 0))

`reffile`	character. MSS image file that has low spatial RMSE and low cloud cover
`fixfile`	character. MSS image file to be spatially warped to match the reference file
`window`	numeric. image subset size used to define cross-correlation calculation. unit is pixels along one side of a square
`search`	numeric. neighborhood search window size in which to find tie-point offset. unit is pixels along one side of a square
`sample`	numeric. target number of tie-points
`refstart`	numeric. c(xcoord,ycoord). reference image coordinate for a pixel identified as common in both the reference and the to-be-warped image. used to calculate an initial offset between the two images.
`fixstart`	numeric. c(xcoord,ycoord). fix image coordinate for a pixel identified as common in both the reference and the to-be-warped image. used to calculate an initial offset between the two images.
