DetectChessboardCornersX: borderBlur set image

When DetectChessboardCornersX is called via a pyramid detector .process will be called multiple times with images of varying dimensions.

borderBlur needs to have setImage called in order for it to know which dimensions to use when considering extend pixel sampling.

Note I'm both unfamiliar with the project and Java, but when I did some debug stepping in my code it looked like colWrap/rowWrap had dimensions 1 always instead of the actual image dimensions.
