Adding more validation
- Added a way to check that the number of inputs of a filter is not more than a filter expects
- Added validation of reftype in SkBitmap::unflatten()
- Added validation on fKD (diffuse lighting constant) and fKS (specular lighting constant) to make sure that they are always non-negative numbers
- Added validation of SkPerlinNoiseShader::fType and SkPerlinNoiseShader::fNumOctaves
