希望 maptalks.three 中的 camera 支持相机类型选择

[liuxinqiong]

maptalks's version and what browser you use?

0.45.1

Issue description

目前 maptalks + maptalks.three 中使用的 camera 由 maptalks 接管，只能是透视相机，无法自主选择正交相机，希望可以自主选择相机类型和自由切换相机类型，使用正交的场景还挺多的

Please provide a reproduction URL (on any jsfiddle like site)

I relied on Google Translate for this but if I understood correctly this issue is about using THREE.js controls instead of maptalks controls. Is there any way this can be achieved now? I'd really like to use orbit-functionality that is available in THREE so that you can rotate camera around a specific point.

@ConstantKrieg Thanks for the suggestion! But I'm afraid using THREE controls is not feasible right now because map has some restrictions on camera's rotation and tilting.

Rotating camera around a specific point is a quite good idea, I'm considering to add something like map.rotateAround(center) based on map.animate function.
