			==== Kernel tech stuff deleted ====
			:I removed the following as I think it of interest to developers only.
			<div {{NotaBeneWidthIndent\|48\|2\|none}} >
			This is a simple 3x3-kernel blurring filter using the kernel [(1−1/2^amount)/2, 1/2^amount, (1−1/2^amount)/2]. The largest allowable argument for Blur is log2(3) (which is about 1.58), which corresponds to a ({{Frac\|1\|3}}, {{Frac\|1\|3}}, {{Frac\|1\|3}}) kernel. A value of 1.0 gets you a ({{Frac\|1\|4}}, {{Frac\|1\|2}}, {{Frac\|1\|4}}) kernel.
