e-paper GDE021A1 display

The closure compiler won't shorten any publically available names. Best thing is to make GDE021A1.prototype.C into just var C, and the compiler will then be able to shorten, inline, and even remove unused elements of that array automatically.

That way your could is easy to view and modify, and small. The only downside is that to add to it, you'd have to change the file itself rather than just adding a prototype.
