Ideally we'd write directly onto the image, instead of a pop-up.
If that can't be done, at least the text in the preview should use the chosen font, since the built-in pixel font might not have all the necessary glyphs. For example, you can choose a TTF font that has support for Kanji, but right now you'll only see what you wrote after you close the pop-up.
Since the chosen font is likely to be illegible at 8px unless it's specifically designed to be a pixel font, we should increase its size, along with the size of the text field.
