In the graphics/graphicx packages there are commands \rotatebox, \resizebox, \scalebox and even \reflectbox. But how can I slant/skew something in the same way? (I'm missing a \skewbox command.)
(Incidentally I looked in the PostScript manual (736 pages). The word "slant" never appears in it, and the word "skew" appears three times, one of them in the sentence "The operators in this group manipulate the CTM to achieve any combination of translation, scaling, rotation, reflection, and skewing of user coordinates onto device coordinates", which proves that at some time some Adobe engineer thought of skewing, but in fact never documented it or wrote any code. Fortunately in the PDF manual version 1.7 there is mention of skewing and even an illustration, on page 118 (the transformation matrix is [1 tan a tan b 1 0 0], I'm interested in horizontal skewing, so that a is 0), so this time Adobe took it seriously. How come this operator has never been included in graphicx? or maybe I overlooked it? Is it because there is no "native" PostScript support for it?)
