Returns the height (in pixels) of the locked part of the specified image.
This includes any padding that the GPU may apply for smaller images. Because of this you should use this height instead of that returned by DX11 GET IMAGE HEIGHT if you
need to know the actual height of the pixel data. Pixels outside the image's displayed width / height (in other words the padding) can be set to whatever; they will not
influence the displayed image.
Take note that the specified image must be locked for this function to succeed..
