I see frame.js allows frames to have a transparency property, which can be set
to true. The only explanation is "Do not display frame sectors where char ==
undefined." 

Sprite.js by default sets its frames to transparent = true.

I guess what I'm still wondering about is how this actually works. So if I have
a small rectangular frame filled with an ANSI or BIN file, nothing will
actually be transparent, because none of the characters will be undefined,
right? I'm thinking the only way I could make use of the transparency is if I
render the characters individually in code, leaving some of them empty.
