Getting an X or Y scale value from a matrix object is not the same as getting a
scale value from an AffineTransform generated from a matrix.

My problems with Matrix and AffineTransform [were just confusion over why
concatenate and preConcatenate are
reversed|https://issues.apache.org/jira/browse/PDFBOX-1960?focusedCommentId=13922210&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13922210],
we're now seeing identical results, as expected. You should not be getting
different results when using a Matrix vs an AffineTransform as they are
performing the same mathematics.
