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
