ANGLE: Invalidate client window area when resetting swap chain
Resizing a window larger results in the newly exposed region being invalidated but the old region is treated as valid. This can result in the old region no longer updating. This has been observed on Windows 7 64-bit with Aero theme using NVIDIA GeForce GTS 250 and driver version 301.42. Invalidate the entire client window area when resetting the swap chain so that it updates properly.
