"required_for_draw" makes it sound like drawing is blocked until this tile has
been initialized. shouldn't it be "visible" instead? which is a concept that
already exists. having both "required_for_draw" and "visible" is confusing..

It is tiles that are visible, high-res and on the active tree. Those are the
ones that are required for drawing without an approximation such as low-res or
checkerboard.

Initialize in the ctor please.

Done.
