Function for **BgcVector2FP32**:
```c
inline void bgc_vector2_copy_fp32(const BgcVector2FP32* from, BgcVector2FP32* to);
inline void bgc_vector2_copy_fp32(const BgcVector2FP32* from, BgcVector2FP32* to);

Function for **BgcVector2FP64**:
```c
inline void bgc_vector2_copy_fp64(const BgcVector2FP64* from, BgcVector2FP64* to);
inline void bgc_vector2_copy_fp64(const BgcVector2FP64* from, BgcVector2FP64* to);

Each of these functions is equivalent to the following lines of code:
```c
to->x1 = from->x1;
to->x2 = from->x2;
to->x1 = from->x1;
to->x2 = from->x2;
```
You should not pass invalid pointers to these functions. The NULL (0) value is also considered invalid.
The **from** and **to** parameters must not be invalid pointers. The NULL (0) value is also considered invalid.
The **from** parameter must be a pointer to a two-dimensional vector whose coordinates are to be copied. The coordinates of the **from** vector will not change after the function call.
