// Make sure to unbind every render texture here because in the next iteration of the loop we might have to reallocate render texture (if the camera size is different)
// We still need to bind correctly default camera target with our depth buffer in case we are currently rendering scene view. It should be the last camera here
// During rendering we use our own depth buffer instead of the one provided by the scene view (because we need to be able to control its life cycle)
// In order for scene view gizmos/icons etc to be depth test correctly, we need to copy the content of our own depth buffer into the scene view depth buffer.
// On subtlety here is that our buffer can be bigger than the camera one so we need to copy only the corresponding portion
// (it's handled automatically by the copy shader because it uses a load in pxiel coordinates based on the target).
// This copy will also have the effect of re-binding this depth buffer correctly for subsequent editor rendering.
// bind depth surface for editor grid/gizmo/selection rendering
// NOTE: This needs to be done before the call to RenderDebug because debug overlays need to update the depth for the scene view as well.
// Make sure RenderDebug does not change the current Render Target
// We make sure the depth buffer is bound because we need it to write depth at near plane for overlays otherwise the editor grid end up visible in them.
