> In a first step, detect all rotations by analyzing the effective text rendering matrix.
In a second step, do a text extraction for each rotation by prepending an appropriate transform
to the page content stream (so that our text has angle == 0) and then filtering any rotated
text. Test file: the file from PDFBOX-4368.
