I think "src" and "dst" would be misleading. This function is used for
blits to the frontbuffer and blits from the frontbuffer. The function
doesn't care about the direction of the blit. It's always the
rectangle used for accessing the frontbuffer that is clipped to the GL
drawable size and location.

The same applies to the parameters of wined3d_clip_blit.

Hmm right, it does seem a bit stupid :-) .
