/* Test the behaviour of the IDirect3DDevice8::CreateImageSurface() method.
 *
 * The expected behaviour (as documented in the original DX8 docs) is that the
 * call returns a surface in the SYSTEMMEM pool. Games like Max Payne 1 and 2
 * depend on this behaviour.
 *
 * A short remark in the DX9 docs however states that the pool of the returned
 * surface object is D3DPOOL_SCRATCH. This is misinformation and would result
 * in screenshots not appearing in the savegame loading menu of both games
 * mentioned above (engine tries to display a texture from the scratch pool).
 *
 * This test verifies that the behaviour described in the original d3d8 docs
 * is the correct one. For more information about this issue, see the MSDN:
 *     d3d9 docs: "Converting to Direct3D 9"
 *     d3d9 reference: "IDirect3DDevice9::CreateOffscreenPlainSurface"
 *     d3d8 reference: "IDirect3DDevice8::CreateImageSurface" */
