Function par_blur_srgb 

pub fn par_blur_srgb(buffer: &mut ImgRefMut<'_, u32>, radius: usize)

Blurs a buffer of 32-bit packed sRGB pixels (0xAARRGGBB) in parallel.

This is a version of par_blur with pre-filled conversion routines that provide good results for blur radii <= 1536. Larger radii may overflow.

Note that this function uses sRGB. For linear, see par_blur_argb.
