<p style="margin: 0px;">It has some nice blur algorithms. </p>
<p style="margin: 0px;"> </p>
<p style="margin: 0px;">But as far as I can see:</p>
<p style="margin: 0px;">BGRA is RGBA 8bit, I need up to 16 bit gray scale.</p>
<p style="margin: 0px;">FilterBlur allocates a copy of an image. I have big images, so I would like to avoid that.</p>
<p>FilterBlur seems to require runtime O(Width*Height*Radius^2). I need Radius 20, so this would be quite slow. </p>
