Fix 30+ broken cross-references in docs/api/math/: - viewport: viewport-getaspectratio/getrect -> getaspectratio/getrect - matrix4: ../color/operator-mul -> operator_mul, operator-index -> operator_index - matrix4/get-*: gettranslation/getscale/getrotation -> get-translation/-scale/-rotation - vector3 operator links: operator_*_assign -> operator-*-assign - vector3 operator links: operator_sub/add -> operator-sub/add - vector3 operator-eq/neq: swap mutual references to use hyphen naming - vector4: ../plane/constructor-default -> constructor_default - Linter fixes: aabb and rectint relative paths corrected

Matrix4x4::GetScale
Vector3 GetScale() const
从变换矩阵中提取缩放分量。计算各列向量的长度作为缩放因子。
参数： （无）
返回： 缩放向量
线程安全： ✅
复杂度： O(1)
示例：
#include "XCEngine/Math/Matrix4.h"
#include "XCEngine/Math/Vector3.h"
using namespace XCEngine::Math;
Matrix4 transform = Matrix4::TRS(
Vector3(0.0f, 0.0f, 0.0f),
Quaternion::Identity(),
Vector3(2.0f, 3.0f, 4.0f)
);
Vector3 scale = transform.GetScale();
// scale = (2.0f, 3.0f, 4.0f)
