+/* Test the behaviour of the IDirect3DDevice8::CreateImageSurface method.
+
+Expected behaviour (and also documented in the original DX8 docs) is that the
+call returns a surface with the SYSTEMMEM pool type. Games like Max Payne 1
+and 2 which use Direct3D8 calls depend on this behaviour.
+
+A short remark in the DX9 docs however states that the pool of the
+returned surface object is of type SCRATCH. This is misinformation and results
+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"
