Is this needed?

Just checked IntSize() and it already initializes its members to 0. Indeed, I
can remove it.

+    kernelSize = FEGaussianBlur::calculateKernelSize(filter, m_stdX, m_stdY);
 
     // We take the half kernel size and multiply it with three, because we run box blur three times.
-    result.inflateX(3 * kernelSizeX * 0.5f);
-    result.inflateY(3 * kernelSizeY * 0.5f);
+    result.inflateX(3 * kernelSize.width() * 0.5f);
+    result.inflateY(3 * kernelSize.height() * 0.5f);
     return result;
