When drawing an interlaced frame, only clear every other line instead of the
entire buffer. Introduced a _drawBuffer pointer which points either to _scaledBuffer or _frameBuffer1. That way, we don't need to copy _frameBuffer1 every time we draw an unscaled frame. (Probably the most common case by far.) Adjusted the Broken Sword 1 DXA player for the second change. (It sneakily avoids copying each frame by using _drawBuffer directly.) svn-id: r24846
