Behaves like the existing avgblur filter, except working on OpenCL
hardware frames. Takes exactly the same options.
Signed-off-by: Mark Thompson <sw@jkqxz.net>
Intended to replace existing opencl mode of the unsharp filter.
Supports many more pixel formats and works without immediate upload
and download of frame data. The options are compatible with the
existing filter.
