Your use of the word "theoretically" reveals much. You would almost certainly be appalled by just how much geometry information is necessary to render a single glyph. Which is why we - and Windows, and OSX - don't do that. When you ask for a glyph at a given transformation matrix, it gets rasterized down to an A8 mask, and we reuse those from then on. (Okay, it's A8R8G8B8 if you're doing subpixel antialiasing). That's the only way you get anything like acceptable performance. If it were easy, we'd already be doing it. - ajax
