Józef Kucia e37b9c74f0 wined3d: Avoid potential out-of-bounds memory access in surface_cpu_blt_colour_fill(). 
Draw rects are derived from the current viewport. It is possible to produce a
clear operation with a draw rect which lies completely outside of one of render
targets in D3D9.

It seems that we never use the CPU blitter for D3D9 render target clears, so it
might not be a problem in practice.
