This adds two functions to the `Drawing` class: `fill_colors()` and `fill_colors_for_write()`. In places where the attribute API was used directly, these functions are now used instead. This is part of #119080. The point is that developers shouldn't need to remember the name, type, default value, and domain of built-in attributes (e.g. used by the renderer).
