I assume you're referring to the rotation done by InlineTextBox. The basic reason for the rotation was that it was a minimal change to the code and allowed a bunch of other drawing functions to remain unchanged. You could certainly eliminate the rotation, but you'd then have to patch all of the InlineTextBox drawing functions (underlines, selection, spell check markers, etc.) to be able to operate horizontally or vertically.
