扩展包围盒。
扩展包围盒。输入值会被除以 2 后添加到 extents 上(标量扩展时,每个轴的 extents 增加 `amount * 0.5f`,即实际尺寸增加 `amount`;向量扩展时,各分量分别处理)。
**参数:**
- `amount` - 扩展量(各方向或统一
- `amount` - 扩展量(标量时各方向均匀扩展,向量时各分量分别扩展
**返回:** `void`
**线程安全:**
**复杂度:** O(1)
**示例:**
```cpp
#include <XCEngine/Math/Bounds.h>
#include <XCEngine/Math/Vector3.h>
using namespace XCEngine::Math;
Bounds bounds(Vector3(0.0f, 0.0f, 0.0f), Vector3(2.0f, 2.0f, 2.0f));
bounds.Expand(1.0f);
// extents becomes (2.0, 2.0, 2.0), size increased by 1 in each direction
bounds.Expand(Vector3(1.0f, 0.0f, 0.0f));
// extents becomes (2.5, 2.0, 2.0), only x extended
```
