My application is this: I have an umlimited amount of text streaming in, 
of which I do not know the contents beforehand,
as they are created dynamically. Think of a stock ticker bar, or a news 
headlines bar scrolling by horizontally, or
vertically, like in a movies credits screen.

I want to layout this text on the screen piecewise, but also be able to 
add visual effects to each glyph appearing.

I'll look into this. Is there any sample code this does this?

This is my first attempt with pangocairo, I'm using it so that my 
application supports all the world lingua/scripts (ideally).

Thanks Behdad and all for all your effort in this,

Best regards,
