customizable AIAF

[dzsemx]

it would be nice to have some options on AIAF focus mode because many times it focuses elsewhere than the subject.
i don't like to use center/flexizone focusing because it's too small, i would like to have selectable AF points like on dslrs

[brainwash]

Yeah, at least an easier to implement feature would be to move the flexizone in increments of its width/height rather than in pixels.
