Title: Declare all variables at the beginning of their function

Some functions are good about this (e.g. `_addPalettes()` and `_dimensions()`), some are kind of in a middle ground (e.g. `stupidIEGradient()`), and some are create variables in lots of places (e.g. `_setOption()`).

It would make the code more readable if all variables were consistently declared at the top of functions.
