[Runtime Bug]: Viewport changes causes 3D stretching

[mmdanggg2]

Describe the bug

When the D3D9 viewport is not set to the full window the rendered image is stretched incorrectly.

How do you reproduce the bug?

Open a game with an altered viewport Deus Ex when in conversations is one example where on a 1280x720 window the viewport is set as such:

	Name	Value	Type
◢	d3dViewport	{X=0 Y=74 Width=1280 ...}	_D3DVIEWPORT9
	X	0	unsigned long
	Y	74	unsigned long
	Width	1280	unsigned long
	Height	495	unsigned long
	MinZ	0.00000000	float
	MaxZ	1.00000000	float

What is the expected behavior?

Non stretch 3D graphics are rendered into the specified viewport.
