gpu, cmaa: blend color like bilinear filter
This CL fixes two points
* blend color like bilinear filter. Current implementation is strange hackish
blend.
* Revert blurCoeff to the original value as the comments explain. The value
might be changed to make hackish blend look good. After revert, CMAA looks
much more similar to MSAA
