oleaut32: added PICTYPE_NONE and PICTYPE_UNINITIALIZED to IPicture::Render with test

[Nikolay Sivov]

Changelog:
    - added PICTYPE_NONE and PICTYPE_UNINITIALIZED to IPicture::Render with test
    - added test for zero dimensions
    - remove some tabs from testfile

P.S. spotted in traces of bugs 6799 and 10050
