The initial target color state is the color state of the stage view being painted to. If we're painting to an arbitrary framebuffer, it's currently hard coded to sRGB/electrical. The content color state is not set on construction, but when starting to paint, it's set to the color state of the stage itself. Whenever an actor is painted, it'll set the color state to the color state of itself. The intention is that offscreen rendering pushes a target color state that causes painting to it to not necessarily be in the stage view color state. Pass color state with offscreen framebuffer, as this avoids hard coding sRGB in the lower level bits of paint contexts. It's still practically hard coded, only that it's derived from somewhere else (e.g. the stage or window actor). Nothing is actually using this yet, but will eventually.
