nope, not exacly ;)

it is a postprocessing, a C++ program :)

btw - next version (now with small lanse-flares like in 35mm camera, 
visible as small circles) I think animation with moving camera would be 
very itneresting.

Currently it takes about 1 min to add flares/glows by my addon, and about 1 
h to render image (due to complicated blob, and radiosity).
