--------------------------------------------------------------
text.getXDirAdj(), text.getYDirAdj(), and text.getWidthDirAdj() don't return
correct values, so your blue boxes were incorrect. So I added some code which
bypasses TextPosition when performing these calculations. I've also structured
my calculations in terms of the space transforms, because "text.getYScale()"
can't work as it assumes that text space is rectangular when projected into
user space, but that's not true as the text matrix can be arbitrary. All space
transforms need to be done with matrixes - scaling factors can't work in the
general case.
I also added some extra code to handle Type 3 fonts.

>
> DrawPrintTextLocations is PrintTextLocations on steroids: after rendering an
> image, the bounds of the font sizes are drawn on it and the images are saved.
> This will allow to see whether a value shown by PrintTextLocations makes
> sense or not. The output as in PrintTextLocations will be kept. The classic
> PrintTextLocations will also be kept so that people don't write support
> questions.
