Reviewed by Tadeu Zagallo.

Depth-only passes which called setScissorRect resulted in nothing
getting rendered because setScissorRect uses the min of the render target
size with the scissor rect, but we weren't correctly setting the render
target width when there were no color attachments.

Correct this by falling back to the size of the depth-stencil texture
when the render target width is zero.
