This header-only library provides a video effect simulating so-called SECAM fire: color noise specific to SECAM analog TV standard. The noise looks like a red, blue and sometimes green horizontal stripes and it might be familiar for those grown up in France, the former Soviet Union or in the Middle East.
Input format is an array of width * height pixels. The pixel consists of
4 bytes: red, green, blue and unused (XRGB). The output is the same.
Refer to ueit.c for basic usage.
