[PATCH] d2d1: Implement ID2D1DeviceContext::CreateImageBrush().

13 May 2022

v3: Add missing AddRef() to ::SetImage(). Thanks Nikolay.
v4: Fix a typo in ::GetImage implementation.
v5: Specify correct brush type, add a FIXME for D2D1_IMAGE_BRUSH_PROPERTIES.sourceRectangle,
    drop d2d_brush_bind_image() helper. Thanks Henri.
