[PATCH 4/5] wined3d: Emit separate clear ops per resource when needed.
We use separate clear operations because our blitters do not support clearing resources of different sizes properly. In the case of the OpenGL blitter, we cannot reliably clear attachments of different sizes using a single glClear() command. The OpenGL spec says: "If the attachment sizes are not all identical, the results of rendering are defined only within the largest area that can fit in all of the attachments. This area is defined as the intersection of rectangles having a lower left of (0, 0) and an upper right of (width, height) for each attachment. Contents of attachments outside this area are undefined after execution of a rendering command (as defined in section 2.4)."
