camera placement - drag zoom cube

[cKleinhuis]

hi there, i just downloaded mandelbulber 2.02, perhaps is the feature already implemented, but if not, the zoom cube that defines the zooming
area, that should get more editable properties, i wanted intuitively drag the zoom radius of that cube, which would be fantastic to behave depending on the current mode (scale, rotate shift) mouse-down=place rectangle, mouse move-vary parameters (control axis, SHIFT-CTRL-ALT disable x/y/z axis ) , mouse up=apply parameters to render camera



and a preview window while doing so ...
