when do i need to do screenPos.y = 1 - screenPos.y;?
This is my calculation rn:
```c++
glm::mat4 VPmatrix = projection * view;
glm::vec4 screenPos = VPmatrix * glm::vec4(instance->pos, 1.0f);
screenPos.x /= screenPos.w;
screenPos.y /= screenPos.w;
screenPos.z /= screenPos.w;
screenPos.x = (screenPos.x + 1.0f) / 2.0f;
screenPos.y = (screenPos.y + 1.0f) / 2.0f;
screenPos.z = (screenPos.z + 1.0f) / 2.0f;
screenPos.x *= viewportWidth;
screenPos.y *= viewportHeight;
```
