pmSourceLocalSky annulus forced on image

[eugene]

the subimage defiend in pmSourceLocalSky needs to be constrained to stay within
the bounds of the image. I've added MAX/MIN functions to require that. (If we
have PS_MAX, PS_MIN defines, we should use those):

peak->x,y is guaranteed to be on image
psS32 SubImageCenterRow = peak->y;
psS32 SubImageCenterCol = peak->x;
psS32 SubImageStartRow = MAX (0, SubImageCenterRow - outerRadiusS32);
psS32 SubImageEndRow = MIN (image->numRows - 1, SubImageCenterRow +

outerRadiusS32);

psS32 SubImageStartCol = MAX (0, SubImageCenterCol - outerRadiusS32);
psS32 SubImageEndCol = MIN (image->numCols - 1, SubImageCenterCol +

outerRadiusS32);

This should be done in current code.
