[FFmpeg-user] drawgraph filter, color formats

[Michael Koch]

Hi,

I'm just making some experiments with the drawgraph filter and it took 
me more than one hour to figure out what was wrong:
The colors of the graphs must be specified in format 0xAABBGGRR, but the 
background color must be in format 0xRRGGBBAA.
That's very confusing!
