[PATCH v2] d2d1: Make ID2D1Device::CreateImageBrush() accept only bitmap as a source image.

[Dmitry Timoshkov]

ID2D1Bitmap derives from ID2D1Image, which in turn derives from ID2D1Resource.
That means that ID2D1Device::CreateImageBrush() can't be really passed anything
but a ID2D1Bitmap* represented as a ID2D1Image*.

I've added QueryInterface+FIXME just in case, probably it could be dropped.

v2: Fix test crashes with image == NULL.

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?
