Patch V1

The spec seems to have been updated to use 1 by 1 as the default mesh. I've also updated that and added some comments.

Using the StringBuilder only inside the CachedShader.cpp file.

Much nicer, thanks a lot. r=me with a few comments:

> Source/WebCore/platform/graphics/filters/CustomFilterShader.cpp:51
> +const char* CustomFilterShader::defaultFragmentShaderString =
> +        "precision mediump float;\n" \

I admit, I like the other solution much more now :-)
It's much more readable, would you mind updating it once again?

> Source/WebCore/platform/graphics/filters/CustomFilterShader.h:79
> +    static const char* defaultVertexShaderString;
> +    static const char* defaultFragmentShaderString;

This could be removed again using this SHADER technique.
