A client wanted to have a method for producing text that has a “cut out” effect, aka Text with “Inner Shadow”. Sort of like if you take a sheet of paper and then cut out the letters, then have light coming from up and slightly to the left so that it throws a shadow into the cut out letters.
For such a scenario you have to get a CGPath that is comprised of the glyphs that make up the text. Those are called glyphs because in some languages they are letters, but in some others they are not. Glyphs are the atomic element that any written language consists of.
Because it reasonably fits with the other work I have already done in DTCoreText I added such a method to both the classes for glyph runs as well as lines. These new methods will be released in the upcoming DTCoreText 1.5 release.
