Vulkan: Fix reserve varying for xfb (take 2) When the xfb extension is used, anything that might result in gl_Position being modified at the end of the shader should cause a varying to be reserved for capturing it. Previously, pre-rotation support was added to the condition (incorrectly, which is fixed in this change), but emulated pre-rotation and no-negative-viewport-support also results in modifications to gl_Position, so they are added to the condition as well.
